Multiplicity and transverse momentum dependence of two- and four-particle correlations in pPb and PbPb collisions

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

Measurements of two- and four-particle angular correlations for charged particles emitted in pPb collisions are presented over a wide range in pseudorapidity and full azimuth. The data, corresponding to an integrated luminosity of approximately 31nb−1, were collected during the 2013 LHC pPb …

Search for new physics with long-lived particles decaying to photons and missing energy in pp collisions at $ \sqrt{s}=7 $ TeV

S. Chatrchyan, V. Khachatryan, A. M. Sirunyan, A. Tumasyan et autres

Abstract A search is performed for long-lived neutral particles decaying into a photon and invisible particles. An example of such a signature is the decay of the lightest neutralino with nonzero lifetime into a gravitino and a photon in gauge-mediated supersymmetry, with …
