June 04 2000 tauface-jetset.F: non-automatic definition of the common block. Corrected. Corrections thanks to J. Holt for sign of costhe introduced. Corrections thanks to J. Holt for search outside the HEPEVT matrices introduced. Change of input parameters for cpp : -traditional Dec 11 2000 PHOTOS: Emission from quarks introduced as option special function C-- can be executed after calling PHOINI C-- blocks emission from quarks if parameter is 1 (enables if 2), physical treatment C-- will be 3, option 2 is not realistic and for tests only, IDUM= IPHQRK(1) ! default is 1 PHOTOS: Emission in decay of pi0 to gamma e+ e- blocked, other blocking entries are easy to place also C-- can be executed after calling PHOINI C-- blocks emission in pi0 to gamma e+ e- if parameter is 1 (enables if 2) IDUM= IPHEKL(1) ! default is 1 Jan 2001 Interface to Pythia available. It can be activated by command make pythia of directory tauola-F at present it works automaitically for HEPEVT dimension 2000 double precision. May .. 2001 Bug in the sigh of cos_theta for tau polarization was corrected. This was not made public until Aug 25 2001 (or even later) Aug 20 2001 To add Novosibirsk parametrization to any versions of TAUOLA available till today special directory tauola-factory was added. In every version cleo aleph cpc parametrization of the form-factors for pi+pi+pi-pi0 and pi+3pi0 can be replaced with the ones based on Novosibirsk data and parametrization. Before calling make cpc (cleo aleph) in directory tauola-F (see documentation) command ./glue in directory tauola-factory should be executed. Aug 25 2001 The spin effects in states of tau+ tau- produced from eplicit or imlicit Z/gamma states were upgraded up to nearly KORALZ standards. Photons can be merged either with beams OR with taus. Bug was fixed, in previous versions photons were wrongly asociated with other beams. This was leading to not very significant miscalcuation of cos_theta (for function calculating tau polarization). Feb 2002 Interface for full spin treatment in Higgs boson decay (scalar or pseudoscalar) is added, it does not change mode of the program use. Some minor bug fixing was introduced. Patch for HEPEVT, alowing program to run properly when second daughter pointer of tau mother is undefined was added. Feb 26 2002 ======================================================================= = NEW VERSION OF THE PACKAGE = ======================================================================= Mar 10, 2002 Thanks to Caterine Biscarat and Tania Moulik for tests and suggestions. Further improvement of the universal interface in cases like: H --> ZZ, Z --> tau tau Z, or production of heavy boson pairs will be introduced in future versions only. There are many possibilities and physics precision goals are probably not so great. Dominant spin effects are anyway in. Dec 21, 2002, Thanks to tests necessary for future developments numerically minor bug was found, see pi+pi+pi-pi0-fix.ps.gz for details. Jan 21, 2003, we have found some problems in Novosibirsk parametrization. We work on this point now. Done at unspecified time. Feb 10, 2003, the points discussed under dates Jan 21, 2003, and Dec 21, 2002, are partially solved (still no updates on control outputs etc.) you need to replace sub-directory TAUOLA/tauola-factory with the content of tauola-factory.tgz file. Later you have to execute (in sub-directory TAUOLA/tauola-factory ) ./glue standard command. Apr 02 2003 Update of PHOTOS weight in W decays as described in CERN-TH/2003-075 are introduced, also correction in default of a key for bremsstrahlung in pi0 decays was corrected. Corrections of Jan 21, 2003, Dec 21, 2002, fully integrated. All demo outputs for all TAUOLA versions are reproduced on RH 7.3.1 CERN distribution. Corrections of universal interface in case of taus having taus as mothers are not installed yet, may be other solutions outside the interface would be better. Apr 07 2003 Comment printouts added to PHOTOS, Corrections to TAUOLA universal interface necessary to run for some options of PYTHIA not yet added. The same is true for use of interface with HERWIG. This items are expected to be updated by summer LHC MC workshop. Apr 07 2003 ======================================================================= = NEW VERSION OF THE PACKAGE = ====================================================================== June 25,2003 New version of tauface-jetset.F which work with all versions of PYTHIA ways of filling HEPEVT common block (as well as with HERWIG way). It survived tests by users, special thanks to Borut Kersevan and also S. Slabospitsky. July 28,2003 extensions for the Higgs boson decay, see preprint CERN-TH/2003-166 for details. Nov 24 2003 All corrections updates and new features as in preprint P. Golonka et al CERN-TH 2003-287 hep-ph/0312240 are included. Jan 25 2004 Consistency checks on outputs etc completed. Jan 27 2004 ======================================================================= = NEW VERSION OF THE PACKAGE = ======================================================================= Oct 08 2004 PHOTOS: With the extension of PHOTOS to new functionalities the following changes in input parameters were introduced and initialization is hard coded as usual in routine PHOCIN: 1) ITRE=.FALSE. Third/fourth order - triple (or quatric) photon switch, see dipswitch IFOUR=(.TRUE.).AND.(ITRE) in routine PHTYPE 2) IEXP=.FALSE. to activate option with multiple photon emission. This option will set: CALL PHCORK(5) ! see below for definition. In case of exponentiation this option is a default because in most cases it is necessary. XPHCUT=0.000 000 1 EXPEPS=1D-4 3) see photos-F/numericalStability.html for more details. TAUOLA: New version of the generating package created, called TAUOLA-BBB it operates exactly as TAUOLA-F and is prepared for managing new versions: authors, BaBar and Belle Oct 10 2004 ======================================================================= = NEW VERSION OF THE PACKAGE = =======================================================================
