Numerical study of multiparticle scattering in theory
We study numerically classical collisions of waves in theory.
These processes correspond to multiparticle scattering in the semiclassical
regime. Parametrizing initial and final wavepackets by energy and particle
numbers , we find classically allowed region in the parameter
space. We describe properties of the scattering solutions at the boundary of
the classically allowed region. We comment on the implications of our results
for multiparticle production in the quantum regime.Comment: 32 pages, 18 figures, journal versio
Gravitational waves from phase transition in split NMSSM
We discuss gravitational wave signal from the strongly first order
electroweak phase transition in the split NMSSM. We find that for sets of
parameters predicting successful electroweak baryogenesis the gravitational
wave signal can be within the reach of future experiments LISA, BBO and
Ultimate DECIGO.Comment: 8 pages, 2 figures, published versio
Gauge theory solitons on noncommutative cylinder
We generalize to noncommutative cylinder the solution generation technique,
originally suggested for gauge theories on noncommutative plane. For this
purpose we construct partial isometry operators and complete set of orthogonal
projectors in the algebra of the cylinder, and an isomorphism between the free
module and its direct sum with the Fock module on the cylinder. We construct
explicitly the gauge theory soliton and evaluate the spectrum of perturbations
about this soliton.Comment: References added; to appear in Theor.Math.Phy
