Numerical study of multiparticle production in theory
S. Demidov, B. Farkhtdinov, D. Levkov
We study multiparticle production in the unbroken -dimensional theory using the semiclassical method of singular solutions. We show that the probabilities of these pr…
Suppression exponent for multiparticle production in theory
S. V. Demidov, B. R. Farkhtdinov, D. G. Levkov
We compute the probability of producing particles from few colliding particles in the unbroken -dimensional theory. To this end we numerically implement semiclass…
Numerical study of multiparticle production in theory: comparison with analytic results
S. V. Demidov, B. R. Farkhtdinov, D. G. Levkov
We develop a numerical method to compute the probabilities of multiparticle production in weakly coupled scalar theories. Our technique is based on D.T. Son's semiclassical method…
Solar mass black holes from neutron stars and bosonic dark matter
Raghuveer Garani, Dmitry Levkov, Peter Tinyakov
Black holes with masses cannot be produced via stellar evolution. A popular scenario of their formation involves transmutation of neutron stars - by accumul…
The fate of small classically stable Q-balls
Dmitry Levkov, Emin Nugaev, Andrei Popescu
The smallest classically stable Q-balls are, in fact, generically metastable: in quantum theory they decay into free particles via collective tunneling. We derive general semiclass…
High-energy limit of collision-induced false vacuum decay
Sergei Demidov, Dmitry Levkov
We develop a consistent semiclassical description of field-theoretic collision-induced tunneling at arbitrary high collision energies. As a playground we consider a (1+1)-dimension…
