CompHEP is a package for automatic calculations of elementary particle decay and collision properties in the lowest order of perturbation theory (the tree approximation). The main idea prescribed… Expand

AbstractThe CompHEP package was developed for calculations of decay and high energy collision processeswith, correspondingly, up to 5 and 4 ﬁnal particles in the lowest order (tree) approximation.… Expand

An approach for classification of diffraction patterns measured in prototypical diffract-and-destroy single-particle imaging experiments at XFELs is presented.Expand

The growth kinetics of AlGaN in NH3 MBE under significant Ga desorption was studied. It was found that the addition of gallium stimulates 2D growth and provides better morphology of films compared to… Expand

Abstract We study top-quark decays in models with light sgoldstinos. The off-diagonal entries in the squark mass matrices can lead to FCNC top two-body decays into a sgoldstino and a c (or u) quark.… Expand

The algorithm based on simple geometrical ideas is suggested for simplification O! tensor expressions which takes into account symmetries, dummy indices, and linear identities with many terms.Expand
