WebApart from the production through light-heavy neutrino mixing, in the linear seesaw, the heavy neutrinos can also be pair-produced at e+e colliders through t-channel exchange of the charged Higgs boson ( rst panel of Fig.1). This cross-section is proportional to Y4 S, and therefore can be large for large YS. WebThe Circular Electron Positron Collider (CEPC) is a future Higgs factory proposed by the Chinese high energy physics community. It will operate at a center-of-mass energy of …
WebIn many cases, higher order corrections have been calculated for inclusive cross sections, but not for fully differential cross sections due to the increased complexity. While inclusive corrections are in good approximation applicable to signal predictions, only fully differential corrections are guaranteed to provide accurate predictions for suppressed backgrounds. WebTwo effects, however, lead to a significant broadening of the Born-level result: (i) initial-state γ radiation (ISR) reduces the cross section and generates an asymmetry of the Higgs...

Yet it can offer insights into other couplings as well, since - in an effective field theory (EFT) parameterisation of potential new physics - both the production cross section and kinematical properties of the Higgs …
