چکیده

We search for a light Higgs boson A0 in the radiative decay Upsilon(3S)-->gammaA(0), A(0)-->tau+tau-, tau+-->e+nu(e)nu(tau), or tau+-->mu+nu(mu)nu(tau). The data sample contains 122x10(6) Upsilon(3S) events recorded with the BABAR detector. We find no evidence for a narrow structure in the studied tau+tau- invariant mass region of 4.03gammaA(0))xB(A(0)-->tau+tau-)>(1.5-16)x10(-5) across the m(tau+tau-) range. We also set a 90% C.L. upper limit on the tau+tau- decay of the eta(b) at B(eta(b)-->tau+tau-)<8%.

Observation of Upsilon(3S)-->tau+tau- and tests of lepton universality in Upsilon decays.

Using data collected with the CLEO III detector at the CESR e+e- collider, we report on a first observation of the decay Upsilon(3S)-->tau+tau-, and precisely measure the ratio of branching fractions of Upsilon(nS), n=1, 2, 3, to tau+tau- and mu+mu- final states, finding agreement with expectations from lepton universality. We derive absolute branching fractions for these decays, and also set a...

Search of the Higgs boson decaying into tau-leptons at ATLAS

The search for the Higgs boson is one of the main goals of the Large Hadron Collider experiments. Both in the Standard Model (SM) and in its minimal supersymmetric extensions (MSSM), one or several new bosons are expected as manifestations of the Higgs field. The tau lepton will be essential for Higgs(es) discovery. In fact, both in SM and in the MSSM, the Higgs boson(s) decaying into tau-pairs...

The Hadronic Tau Decay Signature of a Heavy Charged Higgs Boson at Lhc

The hadronic tau decay channel offers by far the best signature for heavy charged Higgs boson search at the LHC in the large tanβ region. By exploiting the distinct polarization of the tau and its large transverse mass, along with the accompanying missing–pT , one can probe for a charged Higgs boson up to a mass of about 600 GeV in an essentially background-free environment. The transverse mass...

Search for a very light NMSSM Higgs boson produced in decays of the 125 GeV scalar boson and decaying into tau leptons in pp collisions at sqrt(s) = 8 TeV

A search for a very light Higgs boson decaying into a pair of τ leptons is presented within the framework of the next-to-minimal supersymmetric standard model. This search is based on a data set corresponding to an integrated luminosity of 19.7 fb−1 of proton-proton collisions collected by the CMS experiment at a centre-of-mass energy of 8 TeV. The signal is defined by the production of either ...

Search for non-Standard-Model Higgs at the LHC with ATLAS

The discovery prospects of non-Standard Model Higgs bosons with the ATLAS detector are presented. Due to the high branching ratio, results on decay channels that include tau leptons are presented both for the search of the neutral and the charged MSSM Higgs bosons. For the neutral Higgs bosons, results on the muon pair final state are also reported. Furthermore, decay scenarios that include SUS...
