Xenon1T excess from electron recoils of non-relativistic Dark Matter
Dario Buttazzo, Paolo Panci, Daniele Teresi +1
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…
Axion quality from the (anti)symmetric of SU(N)
Marco Ardu, Luca Di Luzio, Giacomo Landini +3
We propose two models where a U(1) Peccei-Quinn global symmetry arises accidentally and is respected up to high-dimensional operators, so that the axion solution to the strong CP p…
Is negative kinetic energy meta-stable?
Christian Gross, Alessandro Strumia, Daniele Teresi +1
We explore the possibility that theories with negative kinetic energy (ghosts) can be meta-stable up to cosmologically long times. In classical mechanics, ghosts undergo spontaneou…
Dark Matter and the XENON1T electron recoil excess
Kristjan Kannike, Martti Raidal, Hardi Veermäe +2
We show that the electron recoil excess around 2 keV claimed by the Xenon collaboration can be fitted by DM or DM-like particles having a fast component with velocity of order $\si…
Relaxing the Higgs mass and its vacuum energy by living at the top of the potential
Alessandro Strumia, Daniele Teresi
We consider an ultra-light scalar coupled to the Higgs in the presence of heavier new physics. In the electroweak broken phase the Higgs gives a tree-level contribution to the ligh…
