Dark gauge-mediated supersymmetry breaking with a massless dark photon / Batell, Brian (Pittsburgh U.) ; Kim, Yechan (KAIST, Taejon) ; Lee, Hye-Sung (KAIST, Taejon) ; Lee, Jiheon (KAIST, Taejon ; CERN)
We study dark gauge-mediated supersymmetry breaking (dark GMSB) in a theory with a new unbroken $U(1)_{D}$ local symmetry and massless dark photon. [...]

Initial-state-driven spin correlations in high-energy nuclear collisions / Giacalone, Giuliano (CERN) ; Speranza, Enrico (CERN)
In the study of spin-polarization phenomena in heavy-ion collisions, it is typically assumed that final-state particles are polarized through thermal vorticity and shear. [...]

Strings from Feynman Diagrams / Gopakumar, Rajesh (Tata Inst.) ; Kaushik, Rishabh (Tata Inst.) ; Komatsu, Shota (CERN) ; Mazenc, Edward A. (Zurich, ETH) ; Sarkar, Debmalya (Harvard U., Phys. Dept. ; Tata Inst.)
For correlators in $\mathcal{N}=4$ Super Yang-Mills preserving half the supersymmetry, we manifestly recast the gauge theory Feynman diagram expansion as a sum over dual closed strings. [...]

Non-local high-$p_t$ transport in anisotropic QCD matter / Barata, João (CERN) ; Du, Xiaojian (U. Santiago de Compostela (main)) ; Sadofyev, Andrey V. (LIP, Lisbon)
We perform a numerical study of non-local partonic transport in anisotropic QCD matter, relevant to the evolution of hard probes in the aftermath of high-energy nuclear scattering events. [...]

PREFACE: A search for long-lived particles at the Large Hadron Collider / Hacisahinoglu, B. (Istanbul U.) ; Ozkorucuklu, S. (Istanbul U.) ; Ovchynnikov, M. (CERN) ; Albrow, M.G. (Fermilab) ; Aydilek, O. (Ankara U.) ; Penzo, A. (Iowa U.)
The Standard Model (SM) fails to explain many problems (neutrino masses, dark matter, and matter-antimatter asymmetry, among others) that may be resolved with new particles beyond the Standard model (BSM). [...]

Measuring $A_\text{FB}^b$ and $R_b$ with exclusive $b$-hadron decays at the FCC-ee / Röhrig, Lars (Dortmund U. ; LPC, Clermont-Ferrand) ; Kröninger, Kevin (Dortmund U.) ; Madar, Romain (LPC, Clermont-Ferrand) ; Monteil, Stéphane (LPC, Clermont-Ferrand) ; Palla, Fabrizio (INFN, Pisa) ; Perez, Emmanuel (CERN)
This paper presents a novel tagging technique to measure the beauty-quark partial decay-width ratio $R_b$ and its forward-backward asymmetry $A_\text{FB}^b$ at the FCC-ee, using $\mathcal{O}(10^{12})$$Z$-boson decays. [...]
