Kl3 and πe3 decays in terms of the Kemmer β current

It is shown with the help of the pion-gauge condition that the divergence of the most general boson current in

Probing a nucleon spin structure at TESLA by the real polarized gamma beam
(1999)
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. ...
Relativistic composite systems and minimal coupling
(1974)
The problem of minimal coupling of relativistic composite systems having internal degrees of freedom is investigated. The ambiguity in the introduction of various internal coordinates with the same mass spectrum can be ...
Elemental abundance analyses with DAO spectrograms - XX. The early A stars epsilon Serpentis, 29 Vulpeculae and sigma Aquarii
(1998)
Elemental abundances of the early A stars epsilon Ser, 29 Vul and sigma Aqr are derived consistently with previous studies of this series using spectrograms obtained with Reticon and CCD detectors. The derived abundances ...
Light-curve and period changes of AB-Andromedae
(1994)
New photoelectric observations of AB And obtained between 1989 and 1992 have been used, together with all available light curves from the literature, to study the light-curve variation of the system and its probable ...
A search for the fourth SM family
(1995)
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 ...
Scalar leptoquark production at TeV energy γp colliders
(1994)
Single scalar leptoquark production in the collisions of high energy γ and proton beams has been investigated. It is shown that future γp colliders will be sensitive to scalar leptoquark masses up to few
