Or sensitivity of experimental distributions toĮxplore spin effects are also addressed, but are far from being exploited. Other topics like methods to evaluate TauSpinner systematic errors New methods, with respect to previous publications, for validation of such an approach are provided. The utility programs, demonstration examples for use of TauSpinner libraries, are prepared and documented. The mainĭistributions for validation of spin content of the user-prepared event sampleĪnd to visualize significance of the τ lepton spin polarization and correlation effects. (polarization and spin correlations) in leptonic τ decays and hadronic τ decays with up to three pions. We review a selection of simple distributions which can be used to monitor the τ spin effects With TauSpinner, the experimental techniques developed over years since LEP 1 times may be The spin effects on experimentally measured distributions and/or modification of the spin effects. No other information stored in the event record is needed.īy calculating spin weights, attributed on the event-by-event basis, it enables numerical evaluation of Τ lepton(s) (also ν τ in case of W-mediated processes) and τ decay products. The information on the polarization and spin correlations is reconstructed from the kinematics of the

Generated samples of events featuring τ leptons produced from intermediate state The TauSpinner package represents a tool which can be used to modify τ spin effects in any Understanding the detector acceptance as well as for the measurements of τ Spin of τ lepton represents an interesting phenomenological quantity which can be usedįor the sake of separation of signal from background or in measuring propertiesĪ proper treatment of τ spin effects in the Monte Carlo simulations is important for It offers a powerful probe in searches for New Physics.
