Leptons 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 کاملThermal photons and dileptons
The study of penetrating probes constitutes a key aspect of the relativistic heavy ion program. In the hadronic sector, jet quenching, for example, has been a striking revelation, and has contributed to expose the qualitatively different physics that appeared in the transition from the SPS to RHIC. In this context, electromagnetic radiation also defines a privileged class of observables owing m...
متن کاملJets and photons.
This Letter applies the concept of "jets," as constructed from calorimeter cell four-vectors, to jets composed (primarily) of photons (or leptons). Thus jets become a superset of both traditional objects such as QCD jets, photons, and electrons, and more unconventional objects such as photon jets and electron jets, defined as collinear photons and electrons, respectively. Since standard objects...
متن کاملPhotons and Static Gravity
The influence of static gravitational field on frequency, wavelength and velocity of photons and on the energy levels of atoms and nuclei is considered in the most elementary way. The interconnection between these phenomena is stressed.
متن کاملLeptonic Photons and Nucleosynthesis
Should U(1) long-range forces be associated to electron, muon and/or tau quantum number then their ”fine structure constants” are seen to be bound by nucleosynthesis data to be less than about 1.7× 10. For τ and μ this is the best upper limit up to date. ∗Laboratoire associé au C.N.R.S. — URA D0063. While the rôle of electric charge, weak isospin, and color is completely clarified in the modern...
