The Mu2e experiment at Fermilab will search for the charged lepton flavor violating process of neutrino-less $mu to e$ coherent conversion in the field of an aluminum nucleus. About $7 cdot 10^{17}$ muons, provided by a dedicated muon beam line in construction at Fermilab, will be stopped in 3 years in the aluminum target. The corresponding single event sensitivity will be $2.5cdot 10^{-17}$. In this paper a brief overview of the physics explored by the $mu to e$ conversion is given, followed by a description of the Mu2e experimental apparatus and the expected detector performance.
This paper is devoted to the first analyses based on the complete data sample collected by the KLOE detector at DAPHNE, the Frascati phi-factory. The result for the BR(K_S -> gammagamma) and the search for the decay K_S->e+e- are presented. Particula
A search for lepton flavor violating decays, kmmp, keep, kpem, kmep and pizem, was performed using the data collected in E865 at the Brookhaven Alternating Gradient Synchrotron. No signal was found in any of the decay modes. At the 90% confidence lev
DANSS is a highly segmented 1~m${}^3$ plastic scintillator detector. Its 2500 one meter long scintillator strips have a Gd-loaded reflective cover. The DANSS detector is placed under an industrial 3.1~$mathrm{GW_{th}}$ reactor of the Kalinin Nuclear
We search for the lepton-flavor-violating decay of the $J/psi$ into an electron and a muon using $(225.3pm2.8)times 10^{6}$ $J/psi$ events collected with the BESIII detector at the BEPCII collider. Four candidate events are found in the signal region
An experiment to search for light sterile neutrinos was conducted at a reactor with a thermal power of 2.8 GW located at the Hanbit nuclear power complex. The search was done with a detector consisting of a ton of Gd-loaded liquid scintillator in a t
