SU(5) Unification with TeV-scale Leptoquarks
Peter Cox, Alexander Kusenko, Olcyr Sumensari +1
It was previously noted that SU(5) unification can be achieved via the simple addition of light scalar leptoquarks from two split multiplets. We explore the parameter space…
Primordial black holes from supersymmetry in the early universe
Eric Cotner, Alexander Kusenko
Supersymmetric extensions of the standard model generically predict that in the early universe a scalar condensate can form and fragment into Q-balls before decaying. If the Q-ball…
Dark Cosmic Rays
Ping-Kai Hu, Alexander Kusenko, Volodymyr Takhistov
If dark matter particles have an electric charge, as in models of millicharged dark matter, such particles should be accelerated in the same astrophysical accelerators that produce…
Astrophysical constraints on dark-matter -balls in the presence of baryon-violating operators
Eric Cotner, Alexander Kusenko
Supersymmetric extensions of the standard model predict the existence of non-topological solitons, -balls. Assuming the standard cosmological history preceded by inflation, -…
PBH Dark Matter in Supergravity Inflation Models
Masahiro Kawasaki, Alexander Kusenko, Yuichiro Tada +1
We propose a novel scenario to produce abundant primordial black holes (PBHs) in new inflation which is a second phase of a double inflation in the supergravity frame work. In our…
Leptogenesis via the 750 GeV pseudoscalar
Alexander Kusenko, Lauren Pearce, Louis Yang
Recently the ATLAS and CMS collaborations have reported evidence of a diphoton excess which may be interpreted as a pseudoscalar boson S with a mass around 750 GeV. To explain the…
Why three generations?
Masahiro Ibe, Alexander Kusenko, Tsutomu T. Yanagida
We discuss an anthropic explanation of why there exist three generations of fermions. If one assumes that the right-handed neutrino sector is responsible for both the matter-antima…
