On the $K^{+} \to π^{0} π^{0} π^{0} e^{+} ν$ decay

E. K. Karkaryan, K. V. Kiselev, V. F. Obraztsov +2

The OKA Collaboration has obtained a new upper limit on the $K^{+} \to π^{0} π^{0} π^{0} e^{+} ν$ decay probability which is 65 times lower than the one currently listed by PDG. However it is…

Simulation of the process $e^{+} e^{-} \to W^{+} W^{-}$ with the heavy right-handed neutrino exchange at 1 TeV future lepton colliders

A. Drutskoy, E. Vasenin

We study potential contribution of the heavy right-handed neutrino exchange in the process $e^{+} e^{-} \to W^{+} W^{-}$ . This process is sensitive to heavy neutrinos with ma…

Energy momentum tensor on and off the light cone: exposition with scalar Yukawa theory

Xianghui Cao, Siqi Xu, Yang Li +4

We compute the gravitational form factors $A_{i}$ , $D_{i}$ and $c ˉ_{i}$ of the scalar Yukawa theory using both the light-cone and covariant perturbation theory at the one-loop level.…

Abnormal solutions of Bethe--Salpeter equation with massless and massive exchanges

Jaume Carbonell1, Vladimir Karmanov, Ekaterina Kupriyanova +1

We summarize the main properties of the so called ''abnormal solutions'' of the Wick--Cutkosky model, i.e. two massive scalar particles interacting via massless scalar exchange ("p…

Polarization and kinematic properties of the splitting functions $q \to W^{\pm} + q^{'}$ and $q \to Z^{0} + q$

Alsu G. Bagdatova, Sergey P. Baranov

We consider the processes $g \to W + q^{'}$ and $q \to Z + q$ and derive the respective splitting functions as functions of two kinematic variables: the longitudinal momentum fracti…

Local quench within the Keldysh technique

A. A. Radovskaya, A. G. Semenov

The problem of quantum scalar field evolution after an instantaneous local perturbation (quench) is considered. A new approach to descriptions of a quench from an arbitrary initial…
