description: Postfit distributions of $\chi$ in the $\mathrm{e}\mu$ channel of the 0j, $m_\mathrm{vis} &gt; 600\,\mathrm{GeV}$ category for the combined 2016-2018 data set after a simultaneous fit of the background and vector LQ signal to the data.

description: A search is presented for a third-generation leptoquark (LQ) coupled exclusively to a $\tau$ lepton and a b quark. The search is based on proton-proton collision data at a center-of-mass energy of $\sqrt{s}=13\,\mathrm{TeV}$ recorded with the CMS detector, corresponding to an integrated luminosity of $138\,\mathrm{fb}^{-1}$. Events with $\tau$ leptons and a varying number of jets originating from b quarks are considered, targeting the single and pair production of LQs, as well as nonresonant $t$-channel LQ exchange. An excess is observed in the data with respect to the background expectation in the combined analysis of all search regions. For a benchmark LQ mass of 2 TeV and a coupling strength of 2.5, the excess reaches local significances of up to 2.8 standard deviations. Upper limits at the $95\%$ confidence level are placed on the LQ production cross section in the LQ mass range 0.5-2.3 TeV, and up to 3 TeV for $t$-channel LQ exchange. Leptoquarks are excluded below masses of 1.22-1.88 TeV for different LQ models and varying coupling strengths up to 2.5. Considering only LQ exchange in the $t$ channel, constraints are placed on LQs with masses and coupling strengths of up to 3 TeV and 3.5, respectively.

title: "Table IV" of "Nuclear matter effects on $J/\psi$ production in asymmetric Cu+Au collisions at $\sqrt{s_{_{NN}}}$ = 200 GeV"

description: Nuclear modification factor ($R_{AA}$) at forward (1.2&lt;$y$&lt;2.2 Cu-going) and backward (-2.2&lt;$y$&lt;-1.2 Au-going) rapidity and forward/backward ratio as a function of centrality (%).
description: We report on $J/{\psi}$ production from asymmetric Cu+Au heavy-ion collisions at $\sqrt{S_{NN}}$=200 $GeV$ at the Relativistic Heavy Ion Collider at both forward (Cu-going direction) and backward (Au-going direction) rapidities. The nuclear modification of $J/{\psi}$ yields in Cu+Au collisions in the Au-going direction is found to be comparable to that in Au+Au collisions when plotted as a function of the number of participating nucleons. In the Cu-going direction, $J/{\psi}$ production shows a stronger suppression. This diverence is comparable in magnitude and has the same sign as the diverence expected from shadowing effects due to stronger low-$x$ gluon suppression in the larger Au nucleus. The relative suppression is opposite to that expected from hot nuclear matter dissociation, since a higher energy density is expected in the Au-going direction.
