Probing an up-phobic Higgs at colliders: the role of -associated production in the democratic 3HDM
Dipankar Das, Teesha Khandelwal, Ipsita Saha
We show that there exists a theoretically well-motivated Higgs sector in which the conventional heavy-Higgs production mechanisms are suppressed. In this limit, the -associated…
Soft Symmetry Breaking as a Nonstandard Source of Mass: Phenomenological Insights from the Two-Higgs-Doublet Model
Dipankar Das, Miguel Levy, Shreya Pandey +2
The soft-breaking parameter, , frequently appearing in the 2HDM scalar potential is much more remarkable than being just a nonstandard parameter that helps make the BSM s…
Flavor puzzle in three Higgs-doublet models: Insights from BGL and lessons from flavor data
Dipankar Das, Miguel Levy, Anugrah M. Prasad
We study a variant of the 3HDM, referred to as the BGL-3HDM, incorporating a symmetry, which can distinguish the primary sources of mass for different fermion…
Sign of the coupling and implication for new physics
Dipankar Das, Anirban Kundu, Miguel Levy +3
The magnitudes of the couplings of the scalar resonance at 125 GeV with the SM particles are found to be consistent with those of the SM Higgs boson. However, the signs are not exp…
New physics interpretations for nonstandard values of
Rafael Boto, Dipankar Das, Jorge C. Romao +2
Current measurement of the signal strength invite us to speculate about possible new physics interactions that exclusively affect without altering the other sign…
