Mass Measurement Using Energy Spectra in Three-body Decays / Agashe, Kaustubh ; Franceschini, Roberto ; Kim, Doojin ; Wardlow, Kyle
In previous works we have demonstrated how the energy distribution of massless decay products in two body decays can be used to measure the mass of decaying particles. [...]

Addressing the LHC flavour anomalies with horizontal gauge symmetries / Crivellin, Andreas ; D'Ambrosio, Giancarlo ; Heeck, Julian
We study the impact of an additional $U(1)'$ gauge symmetry with flavour-dependent charges for quarks and leptons on the LHC flavour anomalies observed in $B \to K^* \mu^+\mu^-$, $R(K) = B \to K \mu^+\mu^-/B \to K e^+e^-$ and $h \to \mu\tau$. [...]
