- 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.
