The flavour of SU(15) composite quarks and leptons
Benoît Assi, Ryan Plestid, Amartya Sengupta +1
We study the flavour structure of an confining chiral gauge theory in which the Standard Model (SM) quarks, leptons, and Higgs emerge as composite bound states. The coup…
Residual Symmetries and Scalar Multiplet Vacuum Alignment in Non-Abelian Flavour Models
Ivo de Medeiros Varzielas, Ming-Shau Liu, Amartya Sengupta +1
We demonstrate that, upon minimizing a renormalizable, single-scalar potential invariant under a non-Abelian symmetry, special orientations in the associated vacuum alignment of th…
Minimal dark origin of a massless Dirac neutrino
P. S. Bhupal Dev, Julia Gehrlein, Amartya Sengupta +1
We propose a gauge-symmetry origin of a rank-two Dirac neutrino mass matrix that enforces one exactly massless neutrino, while being consistent with the oscillation data, as well a…
Signals of Doomsday III: Cosmological signatures of the late time symmetry breaking
Amartya Sengupta, Dejan Stojkovic
Of the universe's original gauge symmetries, only (quantum chromodynamics) and (electromagnetism) remain unbroken today. There is, however, no reason to a…
The signals of doomsday II: Cosmological signatures of late time symmetry breaking
Amartya Sengupta, Dejan Stojkovic, L. C. R. Wijewardhana
Only two gauge symmetries remain unbroken today: and . Both are crucial to our universe as it is and to our form of life. Unless we are special observers a…
The Signals of Doomsday I: False Higgs vacuum decay signatures
Amartya Sengupta, Dejan Stojkovic, De-Chang Dai
The measured standard model parameters indicate that we might live in a false Higgs vacuum, though with a very long lifetime. However, small black holes can serve as catalysers and…
