1 Why the is Boring and Why that is Exciting Tau Review WIN0 Jean Etienne Duboscq Cornell University Thanks to: T. Browder, M. Davier, S. Eidelman, H. Evans, KK Gan, R. Kass, A. Pich, M. Roney, R. Sobie, A. Stahl, R. Stroynowski, J. Swain, J. Urheim, A. Weinstein
2 The Tau in Other Fields The TAU is the last letter of the Greek alphabet and in spiritual terms represents the end or the fulfillment of the revealed word. It is a sign of life and salvation. In the Old Testament the prophet marks those with a Tau who have chosen to reject a sinful lifestyle (Ezekiel 9:4). From: Hospital Sisters of St Francis web site

7 Theorists Prefer General, local, derivative free, lepton number conserving, Lorentz invariant structure for fully leptonic decay SM: g V LL=1 ; 11 others = 0 Lorentz Structure M 4G F S,V,T i, j L,R S,V,T 1,, g ij i i, Experimentalists Prefer Something they can measure Michel Parameters use Observed Quantities 1 d dxd cos x 1 1 x 4 3 8x 6 4 m 1 x P cos 41 x 4 m x 3 8x 6 SM: j x E Emax

10 World Summary of g ij Couplings Coupling to right handed currents excluded Coupling limits from mu are still more stringent than limits from taus No LL limits - need scattering to separate S from V S RR S LR S RL V RR V LR V RL T LR T RL
11 Hadronic Tau Decays Weak current ( final state) -first class currents: V: G=+1, J P =1 - - (n) A: G=-1, J P =0 -,1 + -, a1- (n+1) Opposite G parity = second class suppressed (Isospin violation) - soon to be observed? Use to study inclusive QCD properties, CVC Use as a lab to generate lighter mesons
12 Inclusive Hadronic Decays Spectral Function: Decay product Mass Spectrum, after decay kinematic correction + branching ratio normalization This can be broken up into V,A, +Strange contributions, and studied as a function of q^ vs B x 1 dn x B e N x ds Branching Ratio Norm m 1 sm 1 s m q Spectrum V-A kinematics

26 Tau Review Conclusions 1 Leptonic are apparently very Standard Model Hadronic decays are well measured Hadronic decays provide a lab for QCD with applications well beyond mixing make neutrinoless decay searches exciting CP Violation studies will improve Belle is off to a running start (Babar?) BES/CLEO-C have interesting niches
27 Tau Review Conclusions Remember the on the forehead? Ezekiel 9:4...Walk through the streets of Jerusalem and put a mark on the foreheads of all those who weep and sigh because of the sins they see around them... Why you really should learn about s: Ezekiel 9:5...Follow him through the city and kill everyone whose forehead is not marked. Show no mercy; have no pity!...
