Radiative neutrino masses from dim-7 SMEFT: a simplified multi-scale approach
Kåre Fridell, Lukáš Gráf, Julia Harz +1
Lepton-number-violating interactions occur in the Standard Model Effective Field Theory (SMEFT) at odd dimensions starting from the dimension-5 Weinberg operator. Although the oper…

Leptogenesis and neutrino mass with scalar leptoquarks
Kåre Fridell
Leptoquarks are known to generate a wide range of potentially observable phenomena, and have been searched for in different experiments. We show that the observed baryon asymmetry…

Heavy photophobic ALP at the LHC
Masashi Aiko, Motoi Endo, Kåre Fridell
We study the photophobic ALP model in high-mass regions under LHC Run-II. Since the ALP is predominantly coupled with electroweak gauge bosons such as , , and , and les…
