title: "Figure 9e" of "Search for W' bosons decaying to a top and a bottom quark in leptonic final states in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Observed 95% CL upper limit on the production cross section for a generalized left-right coupling of the W' boson to a t and a b quark for a mass of the W' boson of 5.2 TeV.
description: A search for W' bosons decaying to a top and a bottom quark in final states including electrons or muons is performed with the CMS detector at the LHC. The analyzed data correspond to an integrated luminosity of $138~\mathrm{fb}^{-1}$ of proton-proton collisions at a center-of-mass energy of $13~\mathrm{TeV}$. In general, good agreement with the standard model expectation is observed and no evidence for the existence of the W' boson is found over the mass range examined. The largest observed excess is found for a W' boson mass ($m_{\mathrm{W'}}$) hypothesis of $3.8~\mathrm{TeV}$ with a relative decay width of $1\%$, with a local (global) significance of $2.6$ $(2.0)$ standard deviations. Upper limits on the production cross sections of W' bosons decaying to a top and a bottom quark are set. Left- and right-handed W' bosons with $m_{\mathrm{W'}}$ below $3.9$ and $4.3~\mathrm{TeV}$, respectively, are excluded at the $95\%$ confidence level, under the assumption that the new particle has a narrow decay width. Limits are also set for relative decay widths up to $30\%$. These are the most stringent limits to date on W' bosons decaying to a top and a bottom quark.

title: "Figure A001a" of "Search for W' bosons decaying to a top and a bottom quark in leptonic final states in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Observed and expected 95% CL upper limits on the product of the production cross section for a right-handed W' boson and the W' --&gt; tb branching fraction, as functions of the $m_{W'}$ for a relative width of 10%. The inner (green) band and the outer (yellow) band indicate the regions containing 68 and 95%, respectively, of the distribution of limits expected under the background-only hypothesis. The solid curves show the theoretical expectation at LO in the case that the couplings, and thus the partial widths, are varied together with the total width. In this interpretation the branching fraction of the W' --&gt; tb decays is the same for each value of the width of the W' boson.

title: "Figure 3a" of "Lévy-stable two-pion Bose-Einstein correlations in $\sqrt{s_{NN}}=200$ GeV Au$+$Au collisions"

description: Example fits of Bose-Einstein correlation functions of (a) $\pi^{-}\pi^{-}$ pair with $m_{T}$ between 0.331 and 0.349 GeV/$c^2$ and of (b) $\pi^{+}\pi^{+}$ pair with $m_T$ between 0.655 and 0.675 GeV/$c^2$, as a function $Q$ ≡ |$q_{LCMS}$|, defined in Eq. (26). Both fits show the measured correlation function and the complete fit function (described in VI A), while a Bose-Einstein fit function $C^{(0)}_{2} (Q)$ is also shown, with the Coulomb-corrected data, i.e. the raw data multiplied by $C^{(0)}_{2} (Q)/C_{2}(Q)$. In this analysis we measured 62 such correlation functions (for ++ and -- pairs, in 31 $m_T$ bins), and fitted all of them with the method described in VIA. The first visible point on both panels corresponds to $Q$ values below the accessible range (based on an evaluation of the two-track cuts), these were not taken into account in the fitting.
description: We present a detailed measurement of charged two-pion correlation functions in 0%-30% centrality $\sqrt{s_{NN}}$ = 200 GeV Au+Au collisions by the PHENIX experiment at the Relativistic Heavy Ion Collider. The data are well described by Bose-Einstein correlation functions stemming from Lévy-stable source distributions. Using a fine transverse momentum binning, we extract the correlation strength parameter $\lambda$, the Lévy index of stability $\alpha$ and the Lévy length scale parameter $R$ as a function of average transverse mass of the pair $m_{T}$. We find that the positively and the negatively charged pion pairs yield consistent results, and their correlation functions are represented, within uncertainties, by the same Lévy-stable source functions. The $\lambda$($m_{T}$) measurements indicate a decrease of the strength of the correlations at low $m_{T}$. The Lévy length scale parameter $R$($m_{T}$) decreases with increasing $m_{T}$, following a hydrodynamically predicted type of scaling behavior. The values of the Lévy index of stability $\alpha$ are found to be significantly lower than the Gaussian case of $\alpha$ = 2, but also significantly larger than the conjectured value that may characterize the critical point of a second-order quark-hadron phase transition.
