The CDF-II collaboration's recent high-precision measurement of W boson mass indicates new physics contribution(s) beyond the Standard Model. We investigate the possibility of the well-known canonical Scotogenic model, where dark matter particle running in the loop generates neutrino masses, to explain the CDF-II measurement. We show that the doublet scalar carrying a dark parity charge can account for the W boson mass anomaly through oblique S,T,U parameter corrections. For both scalar and fermionic dark matter possibilities, we simultaneously examine the constraints coming from a) neutrino mass, oscillation, neutrinoless double beta decay and lepton flavour violation experiments, b) from dark matter relic density and direct detection experiments c) from the oblique S,T,U parameter values consistent with CDF-II W boson measurement. We show that the canonical Scotogenic model can simultaneously explain all the aforementioned issues.
The synthesis of a novel azoester homologous series was carried out with a view to understanding and establishing the effect of molecular structure on liquid crystal (LC) behavior of a substance. The novel series consists of eleven homologs, and all are enantiotropically nematogenic without exhibition of any smectic property. Transition and melting temperatures, textures of LC were determined by an optical polarizing microscope equipped with a heating stage. The textures of the nematic phase are threaded or Schlieren. Transition curves of a phase diagram behave in normal manner. The nematic-isotropic transition curve exhibits an odd-even effect. Analytical and spectral data support and confirm the structures of the homologues. Average thermal stability for the nematic is 137.2 • C. The mesomorphic phase length ranges from 15 • C to 50 • C. LC behavior of the novel series is compared with a structurally similar known homologous series. The novel azoester homologous series is entirely nematogenic without exhibition of smectogenic character and of a middle-ordered melting type.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
