Gamma photons from parametric resonance in neutron stars
Juan Garcia-Bellido, Alexander Kusenko
Shock waves in cold nuclear matter, e.g. those induced by a collision of two neutron stars, can generate a large number of gamma photons via parametric resonance. We study the reso…
Pulsar kicks from neutrino oscillations
Alexander Kusenko, Gino Segre
Neutrino oscillations can explain the observed motion of pulsars. We show that two different models of neutrino emission from a cooling neutron star are in good quantitative agreem…
Superball dark matter
Alexander Kusenko
Supersymmetric models predict a natural dark-matter candidate, stable baryonic Q-balls. They could be copiously produced in the early Universe as a by-product of the Affleck-Dine b…
Supersymmetric Q-balls: theory and cosmology
Alexander Kusenko
MSSM predicts the existence of Q-balls, some of which can be entirely stable. Both stable and unstable Q-balls can play an important role in cosmology. In particular, Affleck-Dine…
Neutrino transport: no asymmetry in equilibrium
Alexander Kusenko, Gino Segre, Alexander Vilenkin
A small asymmetry in the flux of neutrinos emitted by a hot newly-born neutron star could explain the observed motions of pulsars. However, even in the presence of parity-violating…
A strongly-interacting phase of the Minimal Supersymmetric Model
Gian F. Giudice, Alexander Kusenko
We argue that in the minimal supersymmetric extension of the Standard Model with a large trilinear coupling both the fundamental Higgs boson and a bound state of squarks (formed vi…
Resonant production of gamma rays in jolted cold neutron stars
Alexander Kusenko
Acoustic shock waves passing through colliding cold neutron stars can cause repetitive superconducting phase transitions in which the proton condensate relaxes to its equilibrium v…
Star Wreck
Alexander Kusenko, Mikhail Shaposhnikov, P. G. Tinyakov +1
Electroweak models with low-energy supersymmetry breaking predict the existence of stable non-topological solitons, Q-balls, that can be produced in the early universe. The relic Q…
Sufficient conditions for the existence of Q-balls in gauge theories
Alexander Kusenko, Mikhail Shaposhnikov, P. G. Tinyakov
We formulate a set of simple sufficient conditions for the existence of Q-balls in gauge theories.
Bound states and resonances in the scalar sector of the MSSM
Alexander Kusenko, Vadim Kuzmin, Igor I. Tkachev
The trilinear couplings of squarks and sleptons to the Higgs bosons can give rise to a spectrum of bound states with exotic quantum numbers, for example, those of a leptoquark.
