Stability of Collective Neutrino Oscillations -- A Distributional Approach
Rupak Majumder, Dwaipayan Mukherjee, Shamik Gupta +1
We study the stability of collective neutrino oscillations using a distributional approach motivated by the statistical mechanics of Kuramoto synchronization. Treating the ensemble…
Sufficient and Necessary Conditions for Collective Neutrino Instability: Fast, Slow, and Mixed
Basudeb Dasgupta, Dwaipayan Mukherjee
Collective neutrino oscillations exhibit instabilities that induce appreciable flavor conversion, with crucial astrophysical implications. While the importance of initial phase-spa…
Constraining Asymmetric Dark Matter using Colliders and Direct Detection
Arnab Roy, Basudeb Dasgupta, Monoranjan Guchait
We reappraise the viability of asymmetric dark matter (ADM) realized as a Dirac fermion coupling dominantly to the Standard Model fermions. Treating the interactions of such a DM p…
Light Shining Through Wall Bounds on Axions From Obscured Magnetars
Dibya S. Chattopadhyay, Basudeb Dasgupta, Amol Dighe +1
Coupling of axions or axion-like particles (ALPs) with photons may lead to photons escaping optically opaque regions by oscillating into ALPs. This phenomenon may be viewed as the…
Can LIGO Detect Non-Annihilating Dark Matter?
Sulagna Bhattacharya, Basudeb Dasgupta, Ranjan Laha +1
Dark matter from the galactic halo can accumulate in neutron stars and transmute them into sub-2.5 black holes if the dark matter particles are heavy, stable, and have…
Elaborating the Ultimate Fate of Fast Collective Neutrino Flavor Oscillations
Soumya Bhattacharyya, Basudeb Dasgupta
Dense clouds of neutrinos and antineutrinos can exhibit fast collective flavor oscillations. Previously, in Phys. Rev. Lett. 126 (2021) 061302, we proposed that such flavor oscilla…
