Heavy neutral leptons N are the most appealing candidates to generate tiny neutrino masses.We studied the signature of heavy neutral leptons in gauged U(1)Lμ-Lτ at a muon collider.Charged under the U(1)Lμ-Lτ symme...

In the framework of the 3-3-1 model with neutral leptons,we investigate lepton-flavor-violating sources based on the Higgs mass spectrum,which has two neutral Higgs identified with the corresponding ones of the two-Hi...

As part of a recent analysis of exclusive two-photon production of W+W- pairs at the LHC, the CMS experiment used di-lepton data to obtain an "effective" photon-photon luminosity. We show how the CMS analysis on th...
J=1/2e MASS (atomic mass units u)The primary determination of an electron's mass comes from measuring the ratio of the mass to that of a nucleus, so that the result is obtained in u (atomic mass units). The conve...
The BABAR experiment has now completed data taking and with an integrated luminosity of 531 fb^-1 of e^+e^- collision data has recorded some 480 million tau-pair events. Various studies of suppressed, rare and forbid...
