Probing Heavy Dark Matter in Red Giants
Sougata Ganguly, Minxi He, Chang Sub Shin +2
Red giants (RGs) provide a promising astrophysical environment for capturing dark matter (DM) via elastic scattering with stellar nuclei. Captured DM particles migrate toward the h…
Bipartite Solution to the Lithium Problem
Sougata Ganguly, Tae Hyun Jung, Tae-Sun Park +1
The primordial lithium problem remains a persistent motivation for new-physics modifications of Big Bang nucleosynthesis, yet the precision of the observed deuterium abundance now…
Revisiting QCD-induced little inflation with chiral density wave state and its implications on pulsar timing array gravitational-wave signals
Tae Hyun Jung, Seyong Kim, Jong-Wan Lee +2
We revisit QCD-induced little inflation in which the Universe starts with a large baryon chemical potential and undergoes a strong first-order QCD phase transition, generating an o…
Revisiting Reactor Anti-Neutrino 5 MeV Bump with C Neutral-Current Interaction
Pouya Bakhti, Min-Gwa Park, Meshkat Rajaee +2
For the first time, we comprehensively examine the potential of a neutral-current interaction of reactor neutrino with C emitting a 3.685 MeV photon to identify the origin o…
