Spin polarization and the Einstein--Podolsky--Rosen paradox in the Monte Carlo event records
Z. Was
In the future high energy physics experiments, the question of properly matching the phenomenological programs that describe different parts of the physics processes (such as hard…
Transverse spin effects in H/A -> tau^+ tau^- ; tau^{+-} -> nu X^{+-}, Monte Carlo approach
Z. Was, M. Worek
The transverse spin effects may be helpful to distinguish between scalar (J^{PC}=0^{++}) or pseudoscalar (J^{PC}=0^{-+}) nature of the spin zero (Higgs) particle once discovered in…
Coherent Exclusive Exponentiation of 2f Processes in e+e- Annihilation
Z. Was, S. Jadach, B. F. L. Ward
In the talk we present the Coherent Exclusive Exponentiation (CEEX) which is implemented in the KK MC event generator for the process e+e- to f bar f +n gamma, f=mu,tau,d,u,s,c,b f…
Spin effects in tau-lepton pair production at LHC
T. Pierzchala, E. Richter-Was, Z. Was +1
Question of the proper incorporation of spin effects in tau lepton decays is often of importance. In present work, case of the Z/gamma to tau+ tau- production mechanism is studied…
The tauola-photos_F environment for versioning the TAUOLA and PHOTOS packages
P. Golonka, E. Richter-Was, Z. Was
We present the system for versioning two packages: the TAUOLA of tau lepton decay and PHOTOS for radiative corrections in decays. The following features can be chosen in automatic…
Two-Fermion Production in Electron-Positron Collisions
Michael Kobel, Zbigniew Was, C. Ainsley +31
This report summarizes the results of the two-fermion working group of the LEP2-MC workshop, held at CERN from 1999 to 2000. Recent developments in the theoretical calculations of…
