A search for the fourth SM family
Arguments favouring the existence of a fourth fermion family in the framework of the Standard Model are given. The masses of the fourth family neutrino, charged lepton and down quark are close to each other within an ...
Pair production of scalar leptoquarks at TeV energy γp colliders
Scalar leptoquark pair production in high energy γ -proton collisions is investigated. We show that future TeV energy γ p colliders are convenient places for searching for scalar leptoquarks up to the masses of a few TeV.
Two anyons with Coulomb interaction in a magnetic field
We have computed numerically the energy spectrum of two anyons with Coulomb (1/r) interaction in a uniform magnetic field. Both non-singular and singular energy eigenfunctions are considered. We solve a second order ...
Upper limit on the magnetic moment of the neutrino
We have recalculated the processes e ν → e ν and e + e − → ν ¯ ν due to an assumed magnetic moment κ of the neutrino (correcting some errors in the previous calculations). Comparing the results with ...
Euler-form actions and the vanishing of the cosmological constant
We investigate the conditions of the vanishing cosmological constant and the presence of gravity and vector gauge fields in a D -dimensional non-Abelian Kaluza-Klein theory based on a dimensionally continued ...
Crystal Structure of Bis[4-(2-oxy-1-naphthylmethyliminomethtyl-N,O:O)-2-penten-2-olato-O]dicopper(II) Complex
The structures of dimeric Cu complexes of Cu2(C11- H10C1N02)2,1 Cu2(C14H11N02)2,2 and Cu2(C12H13N02)2,3 in the presence of different tridentate ONO type Schiffbase ligands are reported from this laboratory. The title compound ...
Pair production of squarks in TeV scale polarized γp collisions
The production of squarks in the high energy collisions of the real photons off the protons is discussed. The polarizations of both photon and proton beams are considered. Although the cross sections for different initial ...
Compensation of lepton charge of matter with relic anti-sneutrinos
We reconsider the idea of the leptonic photon by taking into account the possible compensation of the lepton charge of matter with relic anti-sneutrinos. As a consequence of this compensation we have shown that the available ...
Probing a nucleon spin structure at TESLA by the real polarized gamma beam
The recent proposals concerning the usage of the real polarized gamma beam, obtained by Compton backscattering of the laser photons off the electron beams from either the linear or circular accelerators were considered. ...
