Search for millicharged particles in proton-proton collisions at $\sqrt{s} = 13$ TeV

We report on a search for elementary particles with charges much smaller than the electron charge (e) using a data sample of proton-proton collisions provided by the CERN Large Hadron Collider in 2018, corresponding to an integrated luminosity of 37.5/fb at a center-of-mass energy of 13 TeV. A proto...

Sumario:We report on a search for elementary particles with charges much smaller than the electron charge (e) using a data sample of proton-proton collisions provided by the CERN Large Hadron Collider in 2018, corresponding to an integrated luminosity of 37.5/fb at a center-of-mass energy of 13 TeV. A prototype scintillator-based detector is deployed to conduct the first search at a hadron collider sensitive to particles with charges ≤ 0.1e. The existence of new particles with masses between 20 and 4700 MeV is excluded at 95% confidence level for charges between 0.006e and 0.3e, depending on their mass. New sensitivity is achieved for masses larger than 700 MeV.
