Signatures of Neutrinophilic Pion Dark Matter

Claire Chevallier, Ji-Heng Guo, Giacomo Landini

We study the phenomenology of pion dark matter coupled to neutrinos in a confining sector that dynamically generates both small neutrino masses and dark matter mass from gauge conf…

Probing the neutrino mass through semileptonic decays

Claire Chevallier

We argue that a detailed analysis of semileptonic decays can test the possibility of a massive neutrino. The key observable, related to the forward-backward asymmetry, is exactly z…

Challenging Majorana neutrino effects in $B \to K^{(*)} ν ν$ and $K \to π ν ν$ decays

Asmaa Abada, Claire Chevallier, Luighi P. S. Leal +3

We investigate the contributions of Lepton Number Violating (LNV) effective operators to the rare decays $B \to K^{(*)} ν ν$ and $K \to π ν ν$ . Such operators can modify the kinematic…
