$ZH$ 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. [...]

Low-Energy Probes of No-Scale SU(5) Super-GUTs / Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Evans, Jason L. (Shanghai Jiao Tong U.) ; Nagata, Natsumi (Tokyo U.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.) ; Velasco-Sevilla, L. (Korea Inst. Advanced Study, Seoul)
We explore the possible values of the $\mu \to e \gamma$ branching ratio, $\text{BR}(\mu\rightarrow e\gamma)$, and the electron dipole moment (eEDM), $d_e$, in no-scale SU(5) super-GUT models with the boundary conditions that soft supersymmetry-breaking matter scalar masses vanish at some high input scale, $M_{\rm in}$, above the GUT scale, $M_{\rm GUT}$.
