Asymmetric Dark Matter in Extended Exo-Higgs Scenarios
Hooman Davoudiasl, Pier Paolo Giardino, Cen Zhang
The exo-Higgs model can accommodate a successful baryogenesis mechanism that closely mirrors electroweak baryogenesis in the Standard Model, but avoids its shortcomings. We extend…
Gravitational Waves from Primordial Black Holes and New Weak Scale Phenomena
Hooman Davoudiasl, Pier Paolo Giardino
We entertain the possibility that primordialblack holes of mass --~g, with Schwarzschild radii of , constitute or more…
Probing the Higgs self coupling via single Higgs production at the LHC
Giuseppe Degrassi, Pier Paolo Giardino, Fabio Maltoni +1
We propose a method to determine the trilinear Higgs self coupling that is alternative to the direct measurement of Higgs pair production total cross sections and differential dist…
Exo-Higgs at 750 GeV and Genesis of Baryons
Hooman Davoudiasl, Pier Paolo Giardino, Cen Zhang
We propose that the diphoton excess at 750 GeV reported by ATLAS and CMS is due to the decay of an scalar associated with the breaking of a new symm…
On the two-loop virtual QCD corrections to Higgs boson pair production in the Standard Model
Giuseppe Degrassi, Pier Paolo Giardino, Ramona Gröber
We compute the next-to-leading order virtual QCD corrections to Higgs pair production via gluon fusion. We present analytic results for the two-loop contributions to the spin-0 and…
