Reconstructing S-matrix Phases with Machine Learning
Journal of High Energy PhysicsAn important element of the S-matrix bootstrap program is the relationship between the modulus of an S-matrix element and its phase. Unitarity relates them by an integral equation.

How to define the moving frame of the Unruh-DeWitt detector on manifolds
Journal of High Energy PhysicsThe physical phenomena seen by an observer are defined for a local inertial system that is subjective to the observer. Such a coordinate system is called a “moving frame” because it changes from time to time.

Limits of TMD evolution in SIDIS at moderate Q
EPJ Web of Conferences, 2015 We investigate semi-inclusive deep inelastic scattering measurements in the region of relatively small Q, where sensitivity to nonperturbative transverse momentum dependence can dominate the evolution.

On the nonperturbative charm effects in inclusive $B\to X_{c} l\nu$ decays [PDF]
, 2005 We address the nonperturbative effects associated with soft charm quarks in inclusive B decays. Such corrections are allowed by the OPE, but have largely escaped attention so far.

Reducible contributions to quantum electrodynamics in external fields
Journal of High Energy Physics, 2019 We consider one-particle reducible (1PR) contributions to QED and scalar QED processes in external fields, at one-loop and two-loop order. We investigate three cases in detail: constant crossed fields, constant magnetic fields, and plane waves.

Electroweak vacuum stability in the Higgs-Dilaton theory
Journal of High Energy Physics, 2017 We study the stability of the Electroweak (EW) vacuum in a scale-invariant extension of the Standard Model and General Relativity, known as a Higgs-Dilaton theory.

Tadpole diagrams in constant electromagnetic fields
Journal of High Energy Physics, 2017 We show how all possible one-particle reducible tadpole diagrams in constant electromagnetic fields can be constructed from one-particle irreducible constant-field diagrams.

Propagation of gravitational waves in the nonperturbative spinor vacuum [PDF]
, 2014 The propagation of gravitational waves on the background of a nonperturbative vacuum of a spinor field is considered. It is shown that there are several distinctive features in comparison with the propagation of plane gravitational waves through empty ...
