Multi-lepton probes of new physics and lepton-universality in top-quark interactions / Afik, Yoav (CERN) ; Bar-Shalom, Shaouly (Technion) ; Pal, Kuntal ; Soni, Amarjit (Brookhaven) ; Wudka, Jose (UC, Riverside)
We explore the sensitivity to new physics (NP) in the associated production of top-quarks with leptons $pp \to t \bar t \ell^+ \ell^-$, which leads to the multi-leptons signals $pp \to n \ell + {\tt jets} + \not\!\! E_T$, where $n = 2,3,4$. [...]

Beautiful mixing and CP violation at LHCb / d'Argent, Philippe (CERN)
Precision measurements of beauty hadron decays are sensitive probes of the Standard Model and a promising way to look for new physics phenomena far beyond the energy scale accessible for direct production searches. [...]

Viscous absorption of ultra-high-frequency gravitons / Giovannini, Massimo (CERN ; INFN, Milan Bicocca)
The high-frequency gravitons can be absorbed by the first and second viscosities of the post-inflationary plasma as the corresponding wavelengths reenter the Hubble radius prior to big-bang nucleosynthesis. [...]
