Identification of tau leptons using a convolutional neural network with domain adaptation
A tau lepton identification algorithm, DEEPTAU, based on convolutional neural network techniques, has been developed in the CMS experiment to discriminate reconstructed hadronic decays of tau leptons ($ \tau_\mathrm{h} $) from quark or gluon jets and electrons and muons that are misreconstructed as $ \tau_\mathrm{h} $ candidates. [...]

A Novel Low Sidelobe Level Uniform Transmit/Receive Antenna Arrays for RFID Applications / Rajender, Rathod (U. Pisa (main)) ; Ciarpi, Gabriele (CERN) ; Genovesi, Simone (U. Pisa (main)) ; Rossi, Daniele (U. Pisa (main))
The presence of higher minor lobes in RFID reader antennas results in interference, while the utilization of separate antennas for transmission and reception increases the hardware cost and complexity. [...]

The Price of a Large Electron Yukawa Modification / Allwicher, Lukas (DESY) ; McCullough, Matthew (CERN) ; Renner, Sophie (Glasgow U.) ; Rocha, Duncan (CERN ; Fermilab ; U. Chicago (main)) ; Smith, Benjamin (Glasgow U.)
The theoretical implications of an electron Yukawa modification are considered in the context of a possible Higgs pole run at FCC-ee, aimed at bounding this coupling. [...]

Near-extremal membranes in M-theory / Buchel, Alex (Western Ontario U.) ; Monten, Ruben (CERN)
We consider near-extremal membranes embedded in M-theory, consistently truncated to gauged $\mathcal{N} = 2$ supergravity in four dimensions on the coset space $M^{1,1,0}$. [...]

Search for $K_{\mathrm{S(L)}}^{0} \rightarrow \pi^{+} \pi^{-} \mu^{+} \mu^{-}$ decays at LHCb / LHCb Collaboration
A search for $K_{\mathrm{S(L)}}^{0} \rightarrow π^{+}π^{-}μ^{+}μ^{-}$ decays is performed using proton-proton collision data collected by the LHCb experiment at a centre-of-mass energy of $13\,\mathrm{TeV}$, corresponding to an integrated luminosity of $5.4\,\mathrm{fb^{-1}}$. [...]

Characterizing the initial state and dynamical evolution in XeXe and PbPb collisions using multiparticle cumulants
For the first time, correlations among mixed-order moments of two or three flow harmonics $-$($ v_{n}^{k},v_{m}^{l} $) and ($ v_{n}^{k},v_{m}^{l}, v_{p}^{q} $), with $ k $, $ l $, and $ q $ denoting the respective orders$-$are measured in xenon-xenon (XeXe) collisions and compared with lead-lead (PbPb) results, providing a novel probe of collective behavior in heavy ion collisions.

Nucleosynthesis and CMB bounds on photophilic ALPs: a fresh look / Escudero, Miguel (CERN) ; Garcia-Perez, Clara (CERN ; Zaragoza U.) ; Ovchynnikov, Maksym (CERN)
We provide a fresh look at the cosmological constraints on axion-like particles (ALPs) that couple predominantly to photons, focusing on lifetimes $τ_{a} \lesssim 10^{4}\, {\rm s}$ and masses $m_a\lesssim 10\,{\rm GeV}$. [...]
