abstract
We consider the effects of the injections of energetic photon and electron (or positron) on the big-bang nucleosynthesis. We study the photodissociation of light elements in the early Universe paying particular attention to the case that the injection energy is sub-GeV and derive upper bounds on the primordial abundances of the massive decaying particle as a function of its lifetime. We also discuss a solution of the $^7$Li problem in this framework.

Probing the Phenomenology of Dark Matter from Decoupled Freeze-Out
In a scalar-plus-pseudoscalar mediator model, decoupled freeze-out can produce the observed dark matter relic density via s-wave annihilation while evading CMB limits, though indirect-detection and BBN bounds leave on...

Directional Neutrino Bursts from Spinning and Moving Primordial Black Holes
The paper claims spinning, fast-moving primordial black holes produce collimated high-energy neutrino bursts that IceCube and KM3NeT could detect, and asserts new abundance constraints from their non-observation.
