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…

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 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…
