Telomeres are the ending areas of chromosomes - protective «caps» that ensure the stability of chromosomes. Telomere shortening is one of the most important biological signs of aging and is involved in cellular aging and the «mitotic clock» mecha

The effect of EMF of high frequencies (mobile phones and computers) and the action of radon therapeutic procedures (phenomenological and influencing therapeutic factors) is not still generally known. In addition, we are constantly under the influence

We review the next-to-leading-order cross-sections of the heavy quark–antiquark pair production in linearly polarized photon–photon collision. Implications for the signal of Higgs particles are discussed.

Full O(alpha) electroweak corrections for gamma-gamma-> W+W- are calculated including virtual corrections, soft and hard real photon and Z-boson emission. The corrections are quite large ranging from -2.5% at 500 GeV to -18% at 2 TeV, |cos\theta^\pm|

Perturbative QCD one-loop corrections to the cross sections of the $b\overline{b}(c\overline{c})$ quark pair production in polarized photon-photon collisions, as well as cross sections of the radiative processes $\ensuremath{\gamma}\ensuremath{\gamma

We study the effect of a possible fourth heavy generation of fermions on the Higgs sector of the standard model. We show, from the violation of elastic unitarity, that the scale of strong interactions is well below 1 TeV even with a Higgs mass as low

$\gamma\gamma\to\gamma Z$ scattering at the Photon Linear Collider is considered. Explicit formulas for helicity amplitudes due to $W$ boson loops are presented. It is shown that the $Z\gamma$ pair production will be easily observable at PLC and sepa
