title: "Figures 3-6" of "Cold-nuclear-matter effcts on heavy-quark production in d+Au collisions at sqrt(s_NN)=200 GeV"

description: Heavy flavor electron yield, $d$+Au $\implies$ CHARGED X. Electrons from heavy flavor decays, separated by centrality. The lines represent a fit to the previous $p+p$ result [23], scaled by $N_{coll}$. The inset shows the ratio of photonic background electrons determined by the converter and cocktail methods for Minimum Bias $d$+Au collisions, with error bars (boxes) that represent the statistical uncertainty on the converter data (systematic uncertainty on the photonic-electron cocktail).
description: The PHENIX experiment has measured electrons and positrons at midrapidity from the decays of hadrons containing charm and bottom quarks produced in $d$+Au and $p$+$p$ collisions at $\sqrt{s_{NN}}$ = 200 GeV in the transverse-momentum range 0.85$\leq p^{e}_{T} \leq$8.5 GeV/c. In central $d$+Au collisions, the nuclear modification factor $R_{dA}$ at 1.5 &lt; $p_{T}$ &lt; 5 GeV/c displays evidence of enhancement of these electrons, relative to those produced in $p$+$p$ collisions, and shows that the mass-dependent Cronin enhancement observed at the Relativistic Heavy Ion Collider extends to the heavy $D$ meson family. A comparison with the neutral-pion data suggests that the difference in cold-nuclear-matter effects on light- and heavy-flavor mesons could contribute to the observed differences between the $\pi^{0}$ and heavy-flavor-electron nuclear modification factor $R_{AA}$.

title: "Figure 7" of "Cold-nuclear-matter effcts on heavy-quark production in d+Au collisions at sqrt(s_NN)=200 GeV"

description: Heavy flavor electron $R_{dA}$ 0-100% d+Au collisions. The nuclear modification factors $R_{dA}$ and $R_{AA}$ for minimum bias $d$+Au and Au+Au collisions, for the $\pi^{0}$ and $e^{\pm}_{HF}$. The two boxes on the right side of the plot represent the global uncertainties in the $d$+Au (left) and Au+Au (right) values of $N_{coll}$ . An additional common global scaling uncertainty of 9.7% on $R_{dA}$ and $R_{AA}$ from the $p+p$ reference data is omitted for clarity.

title: "Figure 5" of "Nonperturbative transverse momentum broadening in dihadron angular correlations in $\sqrt{s_{NN}}=200$ GeV proton-nucleus collisions"

description: The Gaussian width differences between $p$+$A$ and $p$+$p$ are shown in two $x_E$ bins as a function of $N_{coll}$.
description: The PHENIX collaboration has measured high-$p_T$ dihadron correlations in $p$+$p$, $p$+Al, and $p$+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The correlations arise from inter- and intra-jet correlations and thus have sensitivity to nonperturbative effects in both the initial and final states. The distributions of $p_{out}$, the transverse momentum component of the associated hadron perpendicular to the trigger hadron, are sensitive to initial and final state transverse momenta. These distributions are measured multi-differentially as a function of $x_E$, the longitudinal momentum fraction of the associated hadron with respect to the trigger hadron. The near-side $p_{out}$ widths, sensitive to fragmentation transverse momentum, show no significant broadening between $p$+Au, $p$+Al, and $p$+$p$. The away-side nonperturbative $p_{out}$ widths are found to be broadened in $p$+Au when compared to $p$+$p$; however, there is no significant broadening in $p$+Al compared to $p$+$p$ collisions. The data also suggest that the away-side pout broadening is a function of $N_{coll}$, the number of binary nucleon-nucleon collisions, in the interaction. The potential implications of these results with regard to initial and final state transverse momentum broadening and energy loss of partons in a nucleus, among other nuclear effects, are discussed.

title: "Figure 2: Vector LQ efficiency, 1j" of "Search for a third-generation leptoquark coupled to a $\tau$ lepton and a b quark through single, pair, and nonresonant production in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Product of acceptance and efficiency of a vector LQ signal as a function of LQ mass under the assumption of exclusive LQ couplings to b quarks and $\tau$ leptons. The acceptances and efficiencies are restricted to the sensitive region of $S_\mathrm{T}^\mathrm{MET} &gt; 800\,\mathrm{GeV}$ and are computed with respect to all possible decay modes of two $\tau$ leptons.
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.
