Neutrino oscillation experiments reveal that neutrinos have very small but finite masses. Since neutrinos have no masses in the standard model, we need to extend the standard model to induce the neutrino masses which coincide with the results of the neutrino oscillation experiments. It is possible that neutrino can have both of Dirac mass and Majorana mass. Majorana mass has the feature that it...
A search for supersymmetry in events with large missing transverse momentum, jets, and at least one hadronically decaying tau lepton has been performed using 3.2 fb−1 of proton–proton collision data at √ s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider in 2015. Two exclusive final states are considered, with either exactly one or at least two tau leptons. No excess over th...
A minimal extension of the standard model to naturally generate small neutrino masses and provide a dark matter candidate is proposed. The dark matter particle is part of a new scalar doublet field that plays a crucial role in radiatively generating neutrino masses. The symmetry that stabilizes the dark matter also suppresses neutrino masses to appear first at three-loop level. Without the need...
Background: Neck mass is one of the most common clinical findings in all age groups. Differential diagnosis of masses includes a range of pathologies from congenital to infectious or neoplasm. Understanding the risk factors of neck masses can help us to assess them properly. The purpose of this study is to obtain the epidemiological and clinical features of different neck masses in Kerman, Iran...
caspase-3, one of the dominant effectors caspases, is activated in almost every model of apoptosis with various signaling pathways. hence, inhibition of caspase-3 has become an attractive target in the treatment of neurodegenerative diseases. caspase-3 inhibitory activities of some 1,2-benzisothiazol-3-one derivatives were modeled by quantitative structure–activity relationship (qsar) using ste...
