title: "Limits on the contact interaction scale $\Lambda$." of "Search for excited $\tau$-leptons and leptoquarks in the final state with $\tau$-leptons and jets in pp collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector"

description: Observed and expected lower 95% CL limit on the contact interaction scale $\Lambda$ as a function of $m_{\tau^\ast}$.
description: A search is reported for excited $\tau$-leptons and leptoquarks in events with two hadronically decaying $\tau$-leptons and two or more jets.
The search uses proton-proton collision data at $\sqrt{s} = 13~\mathrm{TeV}$ recorded by the ATLAS experiment during the Run 2 of the Large Hadron Collider in 2015-2018.
The total integrated luminosity is 139 fb$^{-1}$.
The excited $\tau$-lepton is assumed to be produced and to decay via a four-fermion contact interaction into an ordinary $\tau$-lepton and a quark-antiquark pair.
The leptoquarks are assumed to be produced in pairs via the strong interaction, and each leptoquark is assumed to couple to a charm or lighter quark and a $\tau$-lepton.
No excess over the background prediction is observed.
Excited $\tau$-leptons with masses below 2.8 TeV are excluded at 95% CL in scenarios with the contact interaction scale $\Lambda$ set to 10 TeV.
At the extreme limit of model validity where $\Lambda$ is set equal to the excited $\tau$-lepton mass, excited $\tau$-leptons with masses below 4.6 TeV are excluded.
Leptoquarks with masses below 1.3 TeV are excluded at 95% CL if their branching ratio to a charm quark and a $\tau$-lepton equals 1.
The analysis does not exploit flavour-tagging in the signal region.

title: "Limits on the LQ production cross-section" of "Search for excited $\tau$-leptons and leptoquarks in the final state with $\tau$-leptons and jets in pp collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector"

description: Observed and expected upper 95% CL limit on the LQ production cross-section as a function of $m_\mathrm{LQ}$. The LQ couples to a tau lepton and a c-quark. The limits are also valid for scenarios in which the LQ couples to lighter quarks.

title: "Figure 8a" of "Polarization and cross section of midrapidity J/$\psi$ production in proton-proton collisions at $\sqrt{s}=510$ GeV"

description: $\lambda_{\theta}$ measured in $J/\psi$ transverse momentum bins of 0.0 &lt; $p_T$ &lt; 3.0 GeV/$c$ and 3.0 &lt; $p_T$ &lt; 10.0 GeV/$c$ overlaid with NRQCD predictions in the Helicity and Collins-Soper frames.
description: The PHENIX experiment has measured the spin alignment for inclusive $J/\psi$ $\rightarrow$ $e^+e^−$ decays in $p$+$p$ collisions at $\sqrt{s}$ = 510 GeV at midrapidity. The angular distributions have been measured in three different polarization frames, and the three decay angular coefficients have been extracted in a full two-dimensional analysis. Previously, PHENIX saw large longitudinal net polarization at forward rapidity at the same collision energy. This analysis at midrapidity, complementary to the previous PHENIX results, sees no sizable polarization in the measured transverse momentum range of 0.0 &lt; $p_T$ &lt; 10.0 GeV/$c$. The results are consistent with a previous one-dimensional analysis at midrapidity at $\sqrt{s}$ = 200 GeV. The transverse-momentum-dependent cross section for midrapidity $J/\psi$ production has additionally been measured, and after comparison to world data we find a simple logarithmic dependence of the cross section on $\sqrt{s}$.

title: "Figure 2" of "Measurement of long-range angular correlation and quadrupole anisotropy of pions and (anti)protons in central $d+$Au collisions at $\sqrt{s_{_{NN}}}$=200 GeV"

description: $c_2$ ($p_T$) for track lower-tower pairs from 0-5% $d$+Au collisions and $c_2$ ($p_T$) for pairs in minimum bias $p$+$p$ collisions times the dilution factor.
description: We present azimuthal angular correlations between charged hadrons and energy deposited in calorimeter towers in central $d$+Au and minimum bias $p$+$p$ collisions at $\sqrt{s_{NN}}$ = 200 GeV. The charged hadron is measured at midrapidity $|\eta|$ &lt; 0.35, and the energy is measured at large rapidity (−3.7 &lt; $\eta$ &lt; −3.1, Au-going direction). An enhanced near-side angular correlation across $|\Delta\eta|$ &gt; 2.75 is observed in $d$+Au collisions. Using the event plane method applied to the Au-going energy distribution, we extract the anisotropy strength $v_2$ for inclusive charged hadrons at midrapidity up to $p_T$ = 4.5 GeV/$c$. We also present the measurement of $v_2$ for identified $\pi^{\pm}$ and (anti)protons in central $d$+Au collisions, and observe a mass-ordering pattern similar to that seen in heavy ion collisions. These results are compared with viscous hydrodynamic calculations and measurements from $p$+Pb at $\sqrt{s_{NN}}$ = 5.02 TeV. The magnitude of the mass-ordering in $d$+Au is found to be smaller than that in $p$+Pb collisions, which may indicate smaller radial flow in lower energy $d$+Au collisions.
