Phenomenology of GeV-scale scalar portal
Abstract We review and revise the phenomenology of the scalar portal — a new scalar particle with the mass in GeV range that mixes with the Higgs boson. In particular, we consider production channels B → SK 1(1270) and B → S K 0 ∗ 700 $$ B\to S{K}_0^{\ast }(700) $$ and show that their contribution i...
