The multiplicative conservation of both lepton and baryon numbers, i.e. (−)L and (−)3B , is connected to an axionic solution of the strong CP problem in a supersymmetric, unifiable model of quark and lepton interactions. New particles are predicted at the TeV scale, with verifiable consequences at the Large Hadron Collider. Experimentally, there is no evidence against the conservation of additi...

We show how future solar neutrino experiments in the low energy region can be used to test novel neutrino properties. Information on the Majorana nature or neutrino magnetic moments can be extracted from the observation of electron anti-neutrinos from the Sun and the measurement of an azimuthal asymmetry in the total number of events, respectively. 1. Low-energy electron Anti-neutrinos from the...

We point out that if the fourth generation neutrino is a Majorana fermion, then the astrophysical constraints coupled with the precision measurements of the Z-width at LEP require that the corresponding B-L symmetry is unlikely to be a spontaneously broken global symmetry. If B-L is chosen to be a local symmetry, its breaking scale should be less than a few TeV.

Sighting of magnetic Majorana fermions? Quantum spin liquids—materials whose magnetic spins do not settle into order even at absolute zero temperature—have long captured the interest of physicists. A particularly lofty goal is finding a material that can be described by the so-called Kitaev spin model, a network of spins on a honeycomb lattice that harbors Majorana fermions as its excitations. ...

Gri küf hastalığına neden olan Botrytis cinerea aralarında turunçgil meyvelerininde bulunduğu oldukça geniş konukçu dizisine sahip fungal bir hastalık etmenidir. Bu çalışmada farklı kekik türleri (Origanum onites L., Origanum syriacum Holm., Thymbra spicata L.) ve rezene (Foeniculum vulgare Mill.) bitkilerinden elde edilen uçucu yağların cinerea’nın misel gelişimi, spor çimlenmesi hiflerinin mo...

This study was conducted to evaluate the antifungal activities of Cinnamomum zeylanicum and Origanum vulgare L. essential oil against Aspergillus flavus in culture media and tomato paste. 200 ppm of cinnamon and 500 ppm of oregano completely inhibited A. flavus growth in culture media, while in tomato paste 300 ppm of cinnamon and 200 ppm of oregano had the same effect. Test panel evaluations r...

We construct two SUSY SU (3) ⊗ SU (2) L ⊗ U (1) electroweak models with su-perweak R-parity violation. The scale of R-parity violation in one of the models is determined by the Majorana mass of neutrino and it is very small that leads to the existence of longlived (T ≥ O(10 −4)sec) lightest superparticle. If lightest superpar-ticle is righthanded charged slepton that can be realized within gaug...
