We report on a search for elementary particles with charges much smaller than the electron charge using data sample of proton-proton collisions provided by CERN Large Hadron Collider in 2018, corresponding to an integrated luminosity 37.5 fb$^{-1}$ at center-of-mass energy 13 TeV. A prototype scintillator-based detector is deployed conduct first hadron collider sensitive ${\leq}0.1e$. The existence new masses between 20 and 4700 MeV excluded 95% confidence level $0.006e$ $0.3e$, depending...
We present new results for the suppression of high transverse momentum charmonium [$J/\psi, \psi(2S)$] and bottomonium [$\Upsilon(1S),\Upsilon(2S),\Upsilon(3S)$] states in Pb+Pb collisions at Large Hadron Collider. Our theoretical formalism combines collisional dissociation quarkonia, as they propagate quark-gluon plasma, with thermal wavefunction effects due to screening $Q\bar{Q}$ attractive potential medium. find that a good description relative ground higher excited quarkonium states,...
We report on the expected sensitivity of dedicated scintillator-based detectors at LHC for elementary particles with charges much smaller than electron charge. The dataset provided by a prototype detector is used to characterize performance and provide an accurate background projection. Detector designs, including novel slab configuration, are considered data taking period start in 2022 (Run 3) high luminosity LHC. With Run 3 dataset, existence new masses between 10 MeV 45 GeV could be...
