| Summary: LHAPDF bindings 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. This package provides the shared libraries for the lhapdf6 bindings of pythia.

- Update to version 8.315:
* Fix bug in the Lund symmetric fragmentation function (LSFF).
It concerns the case where diquarks or strange quarks are
assumed to be produced at a later average time than the up and
down quarks.
* Some changes in the Hidden Valley machinery. Several automatic
rescalings of (safety) parameters and constants to allow a
broader range of HV mass scales, including ones below the QCD
one.
* The prefix for custom weights can now be specified with the
setting Weights:prefix which is by default empty.
* The logic behind the construction of parton-shower histories
in CKKW-L merging has been improved.
* Fixed two bugs in PartonLevel.cc:
- When checking if beams are point-like (to determine if ISR
and beam remnants), a lepton check was not performed for the
second beam (B).
- An incorrect check was made when calculating maximum weights
for FSR decays with W/Z.
* Fixed a rare bug in StringFragmentation::setHadronVertices
that caused a segmentation fault when the string endpoints are
c or b quarks, and a quark mass offset correction is
introduced.
* Fixed typos in the documentation for Hadronization Variations
that do not effect that results of Pythia.
* Reverted beam particles back to raw pointers for technical
reasons.
* An incorrect type declaration in 8.314 invalidated the new
option to derive the a and b parameters from the average and
RMS width of the Lund FF, causing this option to fail for any
choice of input parameters, corrected now.
* Fixed a typo in the MPI initialization when using saved grid
which caused an out-of-access memory read.
- Minor re-base of reproducible.patch for update.

updated make file.

* Wed Jul 26 2023 Atri Bhattacharya <badshah400@gmail.com>
- 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.
