This is still unusual as jets go, but not as unusual as the previous case, so the fake background from odd-looking jets is larger.įake taus are common, especially for low-energy taus, so looking for isolated taus (and anti-taus) is harder than looking for isolated electrons and muons. They have only been observed to interact through the weak force, although it is assumed that they also interact gravitationally. you will know how to describe the decays of muon and tau leptons. is based on data from electron1proton collisions at a centreofmass energy. Experimentally, tau leptons are very different from electrons and muons, in that they decay before they pass through the detector. The result is ital msub tau1777.8plus minus0.7plus minus1. ![]() The result obtained from 414 fb(-1) of data. The production of tau leptons in ep collisions is investigated using data. Tau Leptons Of Particular Significance Tau Leptons There are three flavors of charged leptons: electrons, muons and taus. Title: Measurement of the tau-lepton mass Full Record Other RelatedResearch Abstract Using data from the CLEO II detector at CESR, we measure the tau-lepton mass by exploiting the unique kinematics of events in which both taus decay hadronically. ![]() Three charged hadrons of total charge +1 or -1, possibly with neutral hadrons and a neutrino this also looks like a very narrow jet but now with three tracks. What is the mass of objects at the subatomic level and how does the Higgs boson. The mass of the tau lepton has been measured in the decay mode tau -> 3 pi nu(tau) using a pseudomass technique.This type of tau decay has the lowest fake background, since it looks like a very unusual jet, and so this is the best decay mode for identifying a tau. A single charged hadron, possibly with neutral hadrons in this case they form what looks like a very narrow jet with a single track in the tracking detector.An electron or muon, plus a neutrino and anti-neutrino in this case they are registered as an electron or muon by the detector, since the neutrinos cannot be detected (except indirectly through an imbalance in the momentum of what is observed).When they decay, they can either turn into arXiv:2104.There are three flavors of charged leptons: electrons, muons and taus.

The tau lepton has spin 1/2 like the electron and muon leptons and an antiparticle with equal mass but opposite charge. M. Davier, A. Hoecker, B. Malaescu, Z. Zhang, Eur.
