Uncharted Logarithmic Structures in QCD Transverse-Energy Flow / Dasgupta, Mrinal (Manchester U.) ; Fraley, Alexander (Manchester U.) ; Monni, Pier Francesco (CERN) ; Nabeebaccus, Saad (Manchester U.)
We investigate the QCD transverse-energy ($E_T$) flow distribution within an azimuthal region of phase space, defined by an angular interval $Δϕ$ on the plane transverse to a chosen jet axis. [...]

Eigenfunctions of deformed Schrödinger equations / François, Matijn (U. Geneva (main) ; CERN) ; Grassi, Alba (U. Geneva (main) ; CERN) ; Pedroni, Tommaso (SISSA, Trieste ; INFN, Trieste ; IGaP, Trieste)
We study the spectral problems associated with the finite-difference operators $H_N = 2 \cosh(p) + V_N(x)$, where $V_N(x)$ is an arbitrary polynomial potential of degree $N$. [...]

Bounds on Discrete Gauge Symmetries in Supergravity / Baykara, Zihni Kaan (Harvard U. (main)) ; Dierigl, Markus (CERN) ; Kim, Hee-Cheol (POSTECH, Pohang) ; Vafa, Cumrun (Harvard U. (main)) ; Xu, Kai (Harvard U. (main))
We place bounds on the order of enhanced discrete gauge symmetries that act on massless fields and thus arise at subloci of the moduli space in supergravity theories. [...]

Recent experiments have shown that the mean transverse momentum $\langle p_T\rangle$ of outgoing particles increases as a function of the particle multiplicity in ultracentral nucleus-nucleus collisions at collider energies. [...]
