| Summary: Shared library for Pythia - a simulation program for particle collisions | |
Pythia can be used to generate high-energy-physics events, i.e. sets of outgoing particles produced in the interactions between two incoming particles. The objective is to provide as accurate as possible a representation of event properties in a wide range of reactions, within and beyond the Standard Model, with emphasis on those where strong interactions play a role, directly or indirectly, and therefore multihadronic final states are produced. The physics is then not understood well enough to give an exact description; instead the program has to be based on a combination of analytical results and various QCD-based models. Extensive information is provided on all program elements: subroutines and functions, switches and parameters, and particle and process data. This should allow the user to tailor the generation task to the topics of interest. This package provides the shared libraries for pythia.

- Update to version 8.310:
* Production of quarkonia is now available via the simple
timelike shower, see Onia Showers for details.
* Added a new feature that allows producing user-defined
resonances in hadronic rescattering. Newly added particles can
be produced as resonances if they set varWidth = on.
* A number of changes have been made to the heavy ion machinery.
* Included possibility to sample intermediate photon virtuality
also for externally provided events using built-in photon flux
for protons.
* Included possibility to generate DIS events with a
(anti-)neutrino beam.
* The TopRecoilHook, formerly available separately, has now been
integrated into the SimpleTimeShower.
* Introduced a new use plugin system, see Plugins for details.
* The arguments to the setSigmaPtr method are now shared
pointers. Additionally, addSigmaPtr has been introduced with
the previous behaviour of setSigmaPtr, and the new setSigmaPtr
overrides all previously added pointers.
* A similar change has been made for the setResonancePtr method
with the addition of the addResonancePtr method.
* The new Logger class now handles printing such as
initialization information and diagnostic messages. For more
information about this class, see the Logging page.
* The new BeamSetup class has been introduced to handle the beam
configuration, including initializing and changing beam
identities, kinematics and parton distributions.
* Modified interface to LHAPDF6 to allow for multi-threading.
* Updated the Python interface to use pybind11 version 2.10.4
which is compatible with Python 3.11.
* Fix for the Python interface working with gcc13.
* Fixed a bug in the Python interface which prevented main162.py
from running correctly when passing a custom function for
initialization.
* Updated the Lambda_b0 lifetime to c*tau = 0.44 mm. The value
was rounded to two significant digits since PDG and HFLAV do
not quite agree to three digits.
* Included several small fixes in response to running an LLVM
static code analysis.
* Fixed out-of-range access when calling Hist::getYMin and
Hist::getYMax for a histogram that has not been booked.
* Fixed BeamRemnants:unresolvedHadron option that was broken and
had no effect since 8.307.
* Removed use of simple-template-ids in SusyLesHouches.h to make
compliant with C++20.
* Fixed dipole sorting behaviour in ColourReconnection which
resulted in an ordering that depended on the current memory
state of the program.
* Changed the default for Parallelism:balanceLoad to on and
updated the documentation. This ensures each thread will
always generate the same number of events.
* Added the += notation for settings vectors, as well as the
include = fileName directive, which allows for additional
settings files to be directly read in.
* Fixed a bug in the bookkeeping the number of hadrons in the
string fragmentation.
- Major rebase of pythia-remove-rpaths.patch for updated version.
* Sun Feb 27 2022 Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.307:
* Extensions to the hadronic cross sections and beam types used
for hadronic rescattering and cascades in the atmosphere.
* Improvements for hidden valley scenarios.
* A new framework for parallelisation (in addition to the
existing openMP option).
* A number of other technical improvements and bug fixes (full
list here: https://pythia.org/history/index.html).
- Minor rebase of patches to apply cleanly, without fuzz.
* Wed Jan 05 2022 Atri Bhattacharya <badshah400@gmail.com>
- Drop HepMC2 dependency and build without hepmc2 support; largely
superseded by HepMC(3) and this change allows Leap 15.x builds
to proceed without HepMC2-HepMC conflicts.
- Add BuildRequires: fastjet-plugin-siscone-devel which is needed
for one of the tests (test number 111).
* Sun Dec 12 2021 Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.306:
* Fixed the incorrect scale being set when applying the POWHEG
veto, i.e. main31.cc. Note that the number of emissions is
correct in 8.303, but is incorrect in 8.304 and 8.305.
* Fixed repeated initialization causing an ever expanding
physics pointer list in the main Pythia class.
* Fixed issue for HepMC output from Vincia, which would
previously issue warnings about inconsistent mother/daughter
relationships.
* Removed assert statements from Angantyr.
* Shortened Pythia constructor header.
- Rebase pythia-honour-env-cxxflags.patch and
pythia-makefile-destdir-support.patch to apply cleanly.
- Major rebase of pythia-remove-rpaths.patch for updated version.
- Drop patch not required any more:
* pythia-disable-example23-req-MixMax_h.patch: Examples can now
be disabled by passing options to the run script.
- Change BuildRequires to pkgconfig based ones wherever
appropriate.
- More examples need linking against gmp explicitly: add fixes for
all necessary examples to patch pythia-example71-link-gmp.patch
and rename it to pythia-examples-link-gmp.patch.
- Build with Rivet and HepMC(3) support: add HepMC-devel,
pkgconfig(rivet) BuildRequires.
- Update URL and source URL in keeping with upstream.
- Minor improvements to package summaries.
- Run spec-cleaner for minor cleanups.
* Fri Apr 16 2021 Bernhard Wiedemann <bwiedemann@suse.com>
- Fix build for Leap 15.3
* Thu Jan 07 2021 Andreas Schwab <schwab@suse.de>
- Compile with %optflags
* Mon Jan 04 2021 Bernhard Wiedemann <bwiedemann@suse.com>
- Add reproducible.patch to drop build date (boo#1047218)
* Sun Jan 03 2021 Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.245:
* Significant speedup of parton distribution handling.
* Several fixes to avoid out-of-bound evaluation of vectors in
the merging code.
* Several fixes to correctly handle CKKW-L merging of EWkino-
and higgsino-processes have been included.
* Include the functionality for MC@NLO-Delta matching with
aMC@NLO.
* Further bug fixes for the hard process name handling for
weak-boson-fusion-like processes, that led to an incorrect
counting of additional emissions.
* Small fixes to history construction in the presence of
multiple resonances.
* The primordial kT for LHE files is now set by the
BeamRemnants:primordialKThard average value, rather than the
LHE scale, since the latter may be quite low e.g. in the
POWHEG approach.
* The problem of "dangling" gluons causing changing color flows
in SimpleTimeShower for top decays is now fixed.
* Extra check added to SimpleSpaceShower for the case where a
small daughter PDF value can lead to an infinite loop if PDF
variations are switched on.
* Bug fixed in the new possibility to let particles with narrow
widths (such as onia states) obtain a simple Breit-Wigner
distribution, specifically for MPIs, introduced in 8.240.
* An indexing bug, for the scattering lepton in DIS events with
photon radiation allowed, has been fixed.
* Added a few copy constructors to match corresponding
assignment operators, to avoid warnings for some compilers.
* Small fix in cross section calculation of main89.cc.
* Fixes in configure and examples/Makefile to have ROOT examples
work again.
* main**.cmnd, ** = 81-84, 87-88 have been slightly modified
such that linking to LHAPDF6 is not required by default.
* A bug in the XML-to-HTML conversion has led to the
indiscriminate removal of "more" from the HTML manual, notably
in Pythia::moreDecays().
- Add patches:
* pythia-example71-link-gmp.patch: Fix building example 71 by
adding -lgmp to the linker flag.
* pythia-disable-example23-req-MixMax_h.patch: Drop a test that
requires the non-free MixMax.h header (which we delete).
- Use autopatch to setup source dir and apply patches
automatically.
* Sun Mar 01 2020 Atri Bhattacharya <badshah400@gmail.com>
- Update to version 8.244:
* The combination of weight variations, within the context of
uncertainty bands, has not been well documented and therefore
prone to misunderstandings. Now the behaviour of
Info::getGroupWeight() has been made transparent, and the
documentation in Variations has been improved. The main121.cc
example has been modified accordingly.
* Restore the capability to set width and lifetime of a
resonance separately (see change in 8.240). Now the lifetime
is set from the width only if the allowCalc() method of the
resonance class returns true.
* Updated handling of Powheg files, such that files with
multiple/variable number of real emissions can be handled. The
default value of the POWHEG:nFinalparameter has been changed
to -1, see the POWHEG Merging documentation.
* Limit the amount by which transverse smearing of the
space-time quark-antiquark string breakup vertices can give
large shifts, which may translate into unreasonably long
invariant times being assigned to primary hadron production
vertices. This is regulated by the new HadronVertex:maxSmear
parameter. Even so, large hadron production invariant times
may still occur occasionally by imperfections in the
reconstruction around multiple gluon corners, so
HadronVertex:maxTau gives the possibility to reject the
hadrons of such a parton system and try again. Also some other
related changes.
* Fixes for consistent storage of production vertices in units
of mm. Thanks to Christopher Plumberg.
* Number of weights in info reset to 1 for each new init call.
- Drop manual fixes in specfile that are no longer needed:
* No unusual hidden files to delete.
* Buildroot doesn't get copied into config files.
* No more spurious exec permissions in plain files.
