Charm and leptons
Observables related to charm and leptons are of great relevance in heavy ion collisions considering the significant information that they have revealed over the last years. The low mass dielectron yield measured by the CERES collaboration has provided evidence for in-medium effects on the ρ meson. The J/ψ suppression pattern observed by the NA50 collaboration is believed to be an important sign...
متن کاملThe Sybils ’ Advice on Charm ( and Τ Leptons )
The importance of future studies of charm and τ decays is emphasized as probes of New Physics: the most powerful tools are CP asymmetries in charm and τ decays both in partial widths and final state distributions. While these searches for CP violation are instrumentalized in the search for and hopefully future analysis of New Physics, they might also shed light on the CP breaking dynamics requi...
متن کاملSeasonal variation of atmospheric leptons as a probe of charm.
The intensity of TeV atmospheric muons and neutrinos depends on the temperature in the stratosphere. We show that the energy dependence in the 100 TeV range of the correlation with temperature is sensitive to the fraction of muons and neutrinos from decay of charmed hadrons. We discuss the prospects for using the temperature effect as observed in gigaton neutrino detectors to measure the charm ...
متن کاملLeptons and Photons
It is assumed that three lepton families (ν e , e), (ν µ , µ), (ν τ , τ) carry charges, which are sources of electronic, muonic and tauonic massless vector particles, respectively. Various manifestations of these hypothetical photons are discussed. We know only one photon that is coupled to the electric charge of particles. One of the most fundamental properties of the electric charge is its co...
متن کاملOptical leptons
We obtain optical vortices with classical orbital momentum = 1 and spin j = ±1/2 as exact solutions of a system of nonlinear Maxwell equations (NMEs). Two kinds of Kerr-type media, namely, those with and without linear dispersion of the electric and the magnet susceptibility, are investigated. The electric and magnetic fields are represented as sums of circular and linear components. This allow...
