The method to determine the CP nature of Higgs bosons from decays to tau leptons at LC
Malgorzata Worek
We demonstrate how the transverse tau tau spin correlations can be used to determine whether a decaying Higgs boson is a mixed CP eigenstate, thereby directly probe the presence of…
Higgs CP from H/A -> tau tau decay
Malgorzata Worek
We show how the transverse tau tau spin correlations can be used to measure the parity of the Higgs boson and hence to distinguish a CP-even H boson from CP-odd A in the future hig…
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…
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…
