Suppression of baryon number violation in electroweak collisions: Numerical results
F. Bezrukov, D. Levkov, C. Rebbi +2
We present a semiclassical study of the suppression of topology changing, baryon number violating transitions induced by particle collisions in the electroweak theory. We find that…
Transmission through a potential barrier in quantum mechanics of multiple degrees of freedom: complex way to the top
F. Bezrukov, D. Levkov
A semiclassical method for the calculation of tunneling exponent in systems with many degrees of freedom is developed. We find that corresponding classical solution as function of…
Tunneling in quantum cosmology: numerical study of particle creation
D. Levkov, C. Rebbi, V. A. Rubakov
We consider a minisuperspace model for a closed universe with small and positive cosmological constant, filled with a massive scalar field conformally coupled to gravity. In the qu…
Semiclassical Study of Baryon and Lepton Number Violation in High-Energy Electroweak Collisions
F. Bezrukov, D. Levkov, C. Rebbi +2
We make use of a semiclassical method for calculating the suppression exponent for topology changing transitions in high-energy electroweak collisions. In the Standard Model these…
Dynamical tunneling of bound systems through a potential barrier: complex way to the top
F. Bezrukov, D. Levkov
A semiclassical method of complex trajectories for the calculation of the tunneling exponent in systems with many degrees of freedom is further developed. It is supplemented with a…
Real-Time Instantons and Suppression of Collision-Induced Tunneling
D. Levkov, S. Sibiryakov
We consider tunneling processes in QFT induced by collisions of elementary particles. We propose a semiclassical method for estimating the probability of these processes in the lim…
