For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from $\sqrt{{s}_{{}_{NN}}}=2.76\phantom{\rule{0.28em}{0ex}}\text{TeV}$ PbPb and $\sqrt{{s}_{{}_{NN}}}=5.02\phantom{\rule{0.28em}{0ex}}\text{TeV}$ $p\text{Pb}$ collisions collected by the CMS experiment at the …

Abstract Results are reported from a search for physics beyond the standard model in proton-proton collision events with a charged lepton (electron or muon), two jets identified as originating from a bottom quark decay, and significant imbalance in the transverse momentum. The …
