Detecting gravitational waves from cosmological phase transitions with LISA: an update
Chiara Caprini, Mikael Chala, Glauber C. Dorsch +11
We investigate the potential for observing gravitational waves from cosmological phase transitions with LISA in light of recent theoretical and experimental developments. Our analy…
Higgs phenomenology as a probe of sterile neutrinos
Jonathan M. Butterworth, Mikael Chala, Christoph Englert +2
Physics beyond the Standard Model can manifest itself as both new light states and heavy degrees of freedom. In this paper, we assume that the former comprise only a sterile neutri…
Novel -decay signatures of light scalars at high energy facilities
Andrew Blance, Mikael Chala, Maria Ramos +1
We study the phenomenology of light scalars of masses and coupling to heavy flavour-violating vector bosons of mass . For few GeV, this scenario…
Probes of the Standard Model effective field theory extended with a right-handed neutrino
Julien Alcaide, Shankha Banerjee, Mikael Chala +1
If neutrinos are Dirac particles and, as suggested by the so far null LHC results, any new physics lies at energies well above the electroweak scale, the Standard Model effective f…
Mapping the shape of the scalar potential with gravitational waves
Mikael Chala, Valentin V. Khoze, Michael Spannowsky +1
We study the dependence of the observable stochastic gravitational wave background induced by a first-order phase transition on the global properties of the scalar effective potent…
within the Standard Model and beyond
Mikael Chala, Alexander Lenz, Aleksey V. Rusov +1
In light of the recent LHCb observation of CP violation in the charm sector, we review standard model (SM) predictions in the charm sector and in particular for . We get a…
