Democratic three Higgs-doublet models: the custodial limit and wrong-sign Yukawa
Dipankar Das, Miguel Levy, Palash B. Pal +3
We study two novel aspects of democratic 3HDMs -- the custodial limit and the possibility of wrong-sign Yukawa couplings. In the custodial limit, the democratic 3HDMs can easily ne…
Effective Theories of Flavor and the Non-Universal MSSM
Dipankar Das, M. L. López-Ibáñez, M. Jay Pérez +1
Flavor symmetries à la Froggatt-Nielsen~(FN) provide a compelling way to explain the hierarchies of fermionic masses and mixing angles in the Yukawa sector. In Supersymmetric~(SUSY…
Nondecoupling of charged scalars in Higgs decay to two photons and symmetries of the scalar potential
Gautam Bhattacharyya, Dipankar Das
A large class of two- and three-Higgs-doublet models with discrete symmetries has been employed in the literature to address various aspects of flavor physics. We analyse how the p…
Analysis of an extended scalar sector with symmetry
Dipankar Das, Ujjal Kumar Dey
We investigate the scalar potential of a general -symmetric three-Higgs-doublet model. The outcome of our analysis does not depend on the fermionic sector of the model. We ide…
