title: "Table 9" of "Measurement of the cross sections of $\Xi^0_{\rm c}$ and $\Xi^+_{\rm c}$ baryons and branching-fraction ratio BR($\Xi^0_{\rm c} \rightarrow \Xi^-{\rm e}^+\nu_{\rm e}$)/BR($\Xi^0_{\rm c} \rightarrow \Xi^-\pi^+$) in pp collisions at 13 TeV"

description: The $p_{\rm T}-$ integrated cross section of prompt $\Xi^{+}_{\rm c}-$baryon production in pp collisions at 13 TeV for $|y| &lt; 0.5$.
description: The $p_{\rm T}$-differential cross sections of prompt charm-strange baryons $\Xi^0_{\rm c}$ and $\Xi^+_{\rm c}$ were measured at midrapidity ($|y| &lt; 0.5$) in proton--proton (pp) collisions at a centre-of-mass energy $\sqrt{s}=$ 13 TeV with the ALICE detector at the LHC. The $\Xi^0_{\rm c}$ baryon was reconstructed via both the semileptonic decay ($\Xi^{-}{\rm e^{+}}\nu_{\rm e}$) and the hadronic decay ($\Xi^{-}{\rm \pi^{+}}$) channels. The $\Xi^+_{\rm c}$ baryon was reconstructed via the hadronic decay ($\Xi^{-}\pi^{+}\pi^{+}$) channel. The branching-fraction ratio $\rm {\rm BR}(\Xi_c^0\rightarrow~ \Xi^-e^+\nu_e)/\rm {\rm BR}(\Xi_c^0\rightarrow \Xi^{-}\pi^+)=$ 0.95 $\pm$ 0.15 (stat) $\pm$ 0.16 (syst) was consistent with the Belle’s result within 1$\sigma$. The transverse momentum ($p_{\rm T}$) dependence of the $\Xi^0_{\rm c}$- and $\Xi^+_{\rm c}$-baryon production relative to the ${\rm D^0}$-meson and to the $\Sigma^{0,+,++}_{\rm c}$- and $\Lambda^+_{\rm c}$-baryon production are reported. The baryon-to-meson ratio increases towards low $p_{\rm T}$ up to a value of approximately 0.3. The measurements are compared with various models that take different hadronisation mechanisms into consideration. The results provide stringent constraints to these theoretical calculations and additional evidence that different processes are involved in charm hadronisation in electron--positron ($\rm e^+e^-$) and hadronic collisions.

title: "Absolute $p_{\mathrm{T}}^{\gamma}$ cross section" of "Measurement of W$^\pm\gamma$ differential cross sections in proton-proton collisions at $\sqrt{s}$ = 13 TeV and effective field theory constraints"

description: Measured absolute differential $p_{\mathrm{T}}^{\gamma}$ cross section, compared to the MG5_aMC+PY8, GENEVA, MATRIX and MCFM predictions. The differential cross sections $\sigma_{j}(\mathrm{pp}\rightarrow\mathrm{W}^{\pm}\gamma\rightarrow\ell^{\pm}\nu\gamma)$, where $\ell$ denotes all three lepton flavors, are measured in the following fiducial region: $p_{\mathrm{T}}^{\ell} &gt; 30\,\mathrm{GeV}$, $|\eta^{\ell}| &lt; 2.5$, $p_{\mathrm{T}}^{\gamma} &gt; 30\,\mathrm{GeV}$, $|\eta^{\gamma}| &lt; 2.5$, $p_{\mathrm{T}}^{\mathrm{miss}} &gt; 40\,\mathrm{GeV}$, and $\Delta R(\ell, \gamma) &gt; 0.7$. The leptons are dressed by adding the four-momenta of any photons with $\Delta R(\ell, \gamma) &lt; 0.1$ to the four-momentum of the lepton. A smooth-cone photon isolation is also applied, with parameters $\delta_{0}=0.4$, $\epsilon=1.0$, and $n=1$.
description: Differential cross section measurements of $\mathrm{W}^{\pm}\gamma$ production in proton-proton collisions at $\sqrt{s} = 13\,\mathrm{TeV}$ are presented. The data set used in this study was collected with the CMS detector at the CERN LHC in 2016--2018 with an integrated luminosity of $138\,\mathrm{fb}^{-1}$. Candidate events containing an electron or muon, a photon, and missing transverse momentum are selected. The measurements are compared with standard model predictions computed at next-to-leading and next-to-next-to-leading orders in perturbative quantum chromodynamics. Constraints on the presence of TeV-scale new physics affecting the $\mathrm{WW}\gamma$ vertex are determined within an effective field theory framework, focusing on the $\mathcal{O}_{3W}$ operator. A simultaneous measurement of the photon transverse momentum and the azimuthal angle of the charged lepton in a special reference frame is performed. This two-dimensional approach provides up to a factor of ten more sensitivity to the interference between the standard model and the $\mathcal{O}_{3W}$ contribution than using the transverse momentum alone.
