Sources of sub-GZK cosmic rays
P. Tinyakov, I. Tkachev
We analyze the existing evidence that BL Lacertae objects (BL Lacs) are sources of the highest-energy cosmic rays. We argue that three independent signatures observed in the real d…
Instanton propagator in scalar model: exact expression and contribution to instanton induced processes
Yu. A. Kubyshin, P. G. Tinyakov
The propagator in the instanton background in the -lambda phi^4 scalar model in four dimensions is studied. Leading and sub-leading terms of its asymptotics for large momenta and i…
Propagator in the Instanton Background and Instanton-Induced Processes in Scalar Model
Yu. A. Kubyshin, P. G. Tinyakov
The cross section of the multiparticle scattering processes in the non-perturbative sector of the scalar -lambda * phi^4 model is studied within the semiclassical approximation. Fo…
Signatures of Supersymmetric Q-Balls
P. G. Tinyakov
In many supersymmetric extensions of the Standard Model the spectrum of states contains stable non-topological solitons, Q-balls. If formed in the Early Universe in sufficient amou…
Finite Energy Instantons in the O(3) Non-Linear Sigma Model
Peter G. Tinyakov, Emil Mottola, Salman Habib
We consider winding number transitions in the two dimensional O(3) non-linear sigma model, modified by a suitable conformal symmetry breaking term. We discuss the general propertie…
