Formation of primordial black holes through Q-balls
Shinta Kasuya, Masahiro Kawasaki, Alexander Kusenko +1
We study the primordial black hole (PBH) formation from Q-balls that are non-topological solitons in scalar field theories. We develop a formula for calculating the density perturb…
Neutrino masses, matter-antimatter asymmetry, dark matter, and supermassive black hole formation explained with Majorons
Yifan Lu, Zachary S. C. Picker, Alexander Kusenko +1
The spontaneous breaking of a global lepton number symmetry can result in a (pseudo) Nambu-Goldstone boson known as the Majoron. We study a singlet Majoron model that couples to tw…
Revisiting formation of primordial black holes in a supercooled first-order phase transition
Marcos M. Flores, Alexander Kusenko, Misao Sasaki
We reexamine production of primordial black holes in a supercooled phase transition. While a mere overdensity associated with a surviving false-vacuum patch does not imply formatio…
