Publikováno v: EPJ Web of Conferences, Vol 201, p 09001 (2019)

We consider a minimal vectorlike extension of the Standard Model that naturally contains two types of stable neutral particles. They can be interpreted as the Dark Matter candidates. Here, the SM is supplemented by a new fermion (H-quark) sector that

We present and discuss some basic elements of the Standard Model hypercolor extension. Appearance of a set of hyperquarks bound states is resulted from $\sigma-$model using; due to specific symmetries of this minimal extension, there arise stable hyp

Dark Matter in the Standard Model Extension with Singlet Quark

Autor: Beylin, Vitaliy, Kuksa, Vladimir

We analyze the possibility of hadron Dark Matter carriers consisting of singlet quark and the light standard one. It is shown that stable singlet quarks generate effects of new physics which do not contradict to restrictions from precision electrowea

Complex-mass definition and the structure of unstable particle's propagator

Autor: Kuksa, Vladimir

The propagators of unstable particles are considered in the framework of the convolution representation. Spectral function was found for a special case when the propagator of scalar unstable particle has Breight-Wigner form. The expressions for the d
