Dimension-six CP-violating operators of the third-family quarks and their effects at colliders
We listed all possible dimension-six CP-violating SUc(3)×SUL(2)×UY (1) invariant operators involving the third-family quarks, which can be generated by new physics at a higher energy scale. The expressions of these operators after electroweak symmetry breaking and the induced effective couplings Wtb̄, Xbb̄ and Xtt̄ (X = Z, γ, g,H) are also presented. We have evaluated sample contributions of these...
متن کاملDimension-six CP-conserving operators of the third-family quarks and their effects on collider observables
We list all possible dimension-six CP-conserving SUc(3)× SUL(2)× UY (1) invariant operators involving the third-family quarks which could be generated by new physics at a higher scale. Expressions for these operators after electroweak gauge symmetry breaking and the induced effective couplings Wtb̄, Xbb̄ and Xtt̄ (X = Z, γ, g,H) are presented . Analytic expressions for the tree level contributions...

the subjects of the study are only the tefl teachers and students at gilan university. to obtain the desired data, a questionnaire which was based on the theories and disecussions gathered, was used as the main data gathering instrument. to determine the degree of relationship between variables, covariance and pearson product moment correlation coefficient were the formulas applied. the data we...

متن کاملR-Parity Violating Signals at Existing Colliders
Formation of the s-channel slepton resonances at LEP2 or Tevatron at current energies is an exciting possibility in R-parity violating SUSY models. Existing LEP2 and Tevatron data can be exploited to look for sleptons, or to derive bounds on the Yukawa couplings of sleptons to quark and lepton pairs. Invited talk at the 12th Les Rencontres de Physique de la Vallée d’Aoste, La Thuile, Aosta Vall...
