On the Stress Tensor Light-ray Operator Algebra / Belin, Alexandre ; Hofman, Diego M. ; Mathys, Grégoire ; Walters, Matthew T.
We study correlation functions involving generalized ANEC operators of the form $\int dx^- \left(x^-\right)^{n+2} T_{--}(\vec{x})$ in four dimensions. [...]

$ZH$ production in gluon fusion: two-loop amplitudes with full top quark mass dependence / Chen, Long ; Heinrich, Gudrun ; Jones, Stephen P. ; Kerner, Matthias ; Klappert, Jonas ; Schlenk, Johannes
We present results for the two-loop helicity amplitudes entering the NLO QCD corrections to the production of a Higgs boson in association with a $Z$-boson in gluon fusion. [...]

Tetra-quarks, penta-quarks and the like: old and new views / Rossi, Giancarlo ; Veneziano, Gabriele
In this talk, after a short overview of the history of the discovery of tetra-quarks and penta-quarks, we will discuss a possible interpretation of such states in the framework of a 40-years-old "string junction" picture that allows a unified QCD description of ordinary mesons and baryons as well as multi-quark resonances..

Wash-In Leptogenesis / Domcke, Valerie ; Kamada, Kohei ; Mukaida, Kyohei ; Schmitz, Kai ; Yamada, Masaki
We present a new leptogenesis mechanism based on the standard type-I seesaw model that successfully operates at right-handed-neutrino masses as low as a few 100 TeV. [...]

Xenon1T excess from electron recoils of non-relativistic Dark Matter / Buttazzo, Dario ; Panci, Paolo ; Teresi, Daniele ; Ziegler, Robert
We show that electron recoils induced by non-relativistic Dark Matter interactions can fit well the recently reported Xenon1T excess, if they are mediated by a light pseudo-scalar in the MeV range. [...]

Function Theory for Multiloop Feynman Integrals / Duhr, Claude
Precise predictions for collider observables require the computation of higher orders in perturbation theory. This usually involves the evaluation of complicated multiloop integrals, which typically give rise to complicated special functions. [...]
