The addition of an Abelian family symmetry to the Minimal Supersymmetric Standard Model reproduces the observed hierarchies of quark and lepton masses and quark mixing angles, only if it is anomalous. Green-Schwarz compensation of its anomalies requires the electroweak mixing angle to be sin2 θw = 3/8 at the string scale, without any assumed GUT structure, suggesting a superstring origin for th...

'WHO Standard Acupuncture Point Locations in the Western Pacific Region (WHO Standard) was released in 2008. Initially, there were 92/361 controversial acupuncture points (acupoints). Through seven informal consultations and four task force team meetings, 86 points were agreed upon among the 92 controversial acupoints, leaving 6 remaining controversial acupoints, demanding active research in th...

altogether 20 groundwater samples were collected around the lakan pb and zn mine in iran. samples were analyzed for 8 constituents including fe, pb, hg, mn, zn, cn, so4 and cl using standard method. the results show that the average concentrations of constituents were 0.01, 0.60, 0.10, 0.01, 0.40, 35, 0.01 and 5.95 mg/kg for fe, mn, pb, zn, hg, so4, cn and cl, respectively. the computed contami...

'The law imposes the duty of care: but the standard of care is a matter of medical judgment'. So says Lord Scarman, outlining the hitherto accepted 'Bolam' standard, in his recent speech in the House of Lords decision of Sidaway v Bethlem Royal Hospital, reflecting earlier judicial dicta suggesting that it is for the medical profession rather than the courts to determine whether or not a medica...

Different scenarios of new physics beyond the standard model give rise to a direct coupling of right-handed quarks to W bosons. We will discuss how the prediction of the Callan-Treiman low energy theorem for the scalar Kπ form factor in combination with recent data on K μ3 decays can serve as a stringent test of the standard model (SM) and possible extensions, in particular right-handed charged...

We study the discovery potential of the Tevatron for a Z ′ gauge boson. We introduce a parametrization of the Z ′ signal which provides a convenient bridge between collider searches and specific Z ′ models. The cross section for pp → Z X → l+l−X depends primarily on the Z ′ mass and the Z ′ decay branching fraction into leptons times the average square coupling to up and down quarks. If the qua...

We study the rare decays of B + c → D (*)+ q l ¯ l (q = d, s and l = ν l , e, µ, τ) in the standard model. The form factors are evaluated in the light front and constituent quark models, respectively. We find that the decay branching ratios calculated in the two models for B + c → D + q l ¯ l agree well with each other, whereas those for B
