CP asymmetry and visible decay in neutrino oscillations on a quantum computer
Amartya Sengupta, Sidhartha Samtani, Ani Girgvliani +1
We use quantum simulation to study how visible neutrino decay modifies the vacuum CP asymmetry in muon-to-electron oscillations within a neutrino scenario. The decay channel…
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…
Environment Dependent Electron Mass and the H-Tension
Rance Solomon, Garvita Agarwal, Dejan Stojkovic
A difference in the electron mass at recombination from the measured value today has been shown to relieve the Hubble tension. In this article we propose a simple mechanism that wo…
Connecting the Higgs Potential and Primordial Black Holes
De-Chang Dai, Ruth Gregory, Dejan Stojkovic
It was recently demonstrated that small small black holes can act as seeds for nucleating decay of the metastable Higgs vacuum, dramatically increasing the tunneling probability. A…
