Search for trilepton resonances from chargino and neutralino pair production in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector
A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an $R$-parity-violating coupling into a lepton and a $W, \, Z$, or Higgs boson. [...]

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..

MARTY, a new C++ framework for automated symbolic calculations in Beyond the Standard Model physics / Uhlrich, G. ; Mahmoudi, F. ; Arbey, A.
Theoretical calculations Beyond the Standard Model (BSM) constitute a challenge for high energy physicists, but are necessary when searching for New Physics. [...]

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. [...]

Observation of a new excited $D_s^+$ meson in $B^0\to D^+D^-K^+\pi^-$ decays / LHCb Collaboration
Using $pp$ collision data corresponding to an integrated luminosity of $5.4\,{\rm fb}^{-1}$ collected with the LHCb detector at a centre-of-mass energy of $13\,{\rm TeV}$, the $B^0\to D^+D^-K^+\pi^-$ decay is studied. [...]
