Search for heavy Higgs bosons decaying into two tau leptons with the ATLAS detector using $pp$ collisions at $\sqrt{s}=13$ TeV
A search for heavy neutral Higgs bosons is performed using the LHC Run 2 data, corresponding to an integrated luminosity of 139 fb$^{-1}$ of proton$-$proton collisions at $\sqrt{s}=13$ TeV recorded with the ATLAS detector. [...]

Quark Flavor Phenomenology of the QCD Axion / Martin Camalich, Jorge (IAC, La Laguna ; Laguna U., Tenerife) ; Pospelov, Maxim (Minnesota U. ; Minnesota U., Theor. Phys. Inst.) ; Vuong, Hoa (LPSC, Grenoble) ; Ziegler, Robert (CERN ; KIT, Karlsruhe, TTP) ; Zupan, Jure (Cincinnati U.)
Axion models with generation-dependent Peccei-Quinn charges can lead to flavor-changing neutral currents, thus motivating QCD axion searches at precision flavor experiments. [...]

$T\bar T$-deformation and long range spin chains / Pozsgay, Balázs ; Jiang, Yunfeng ; Takács, Gábor
We point out that two classes of deformations of integrable models, developed completely independently, have deep connections and share the same algebraic origin. [...]

Search for dijet resonances in events with an isolated charged lepton using $\sqrt{s} = 13$ TeV proton$-$proton collision data collected by the ATLAS detector
A search for dijet resonances in events with at least one isolated charged lepton is performed using $139~{\text{fb}}^{-1}$ of $\sqrt{s}=13$ TeV proton$-$proton collision data recorded by the ATLAS detector at the LHC. [...]

First combined measurement of the muon neutrino and antineutrino charged-current cross section without pions in the final state at T2K / T2K Collaboration
This paper presents the first combined measurement of the double-differential muon neutrino and antineutrino charged-current cross sections with no pions in the final state on hydrocarbon at the off-axis near detector of the T2K experiment. [...]

Cylinder partition function of the 6-vertex model from algebraic geometry / Bajnok, Zoltan ; Jacobsen, Jesper Lykke ; Jiang, Yunfeng ; Nepomechie, Rafael I. ; Zhang, Yang
We compute the exact partition function of the isotropic 6-vertex model on a cylinder geometry with free boundary conditions, for lattices of intermediate size, using Bethe ansatz and algebraic geometry. [...]

Probing QCD using top quark pair production at $\sqrt{s} = 13~\mathrm{TeV}$ in CMS / Defranchis, Matteo M.
Measurements of the top quark-antiquark pair production cross section, $\sigma_\mathrm{t\bar{t}}$, can be used to constrain the strong coupling constant, $\alpha_{S}$, the top quark mass, $m_\mathrm{t}$, and the parton distribution functions (PDFs). [...]
