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. [...]

Neutrino thermalization via randomization on a quantum processor / Kiss, Oriel (Geneva U. ; CERN ; U. Trento (main)) ; Tavernelli, Ivano (Unlisted, CH) ; Tacchino, Francesco (Unlisted, CH) ; Lacroix, Denis (IJCLab, Orsay) ; Roggero, Alessandro (U. Trento (main) ; TIFPA-INFN, Trento)
The dynamical evolution of neutrino flavor in supernovae can be modeled by an all-to-all spin Hamiltonian with random couplings. [...]

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 $m_a\lesssim 10\,{\rm GeV}$. [...]

opbasis - a Python package to derive minimal operator bases / Husung, Nikolai (CERN ; Madrid, IFT ; Madrid, Autonoma U.)
Finding a complete and yet minimal on-shell basis of operators of a given mass-dimension that are compatible with a specific set of transformation properties is the first step in any Effective Field Theory description. [...]
