The P and Y spectroscopies are analyzed in the framework of a recently proposed potential model which incorporates linear confinement and asymptotic freedom. Given the Regge slope a ' (a ' taken to be 1 GeV ') and the quantum-chromodynamics (QCD) scale parameter A (AM, taken to be 0.5 GeV, where MS refers to the modified minimal-subtraction scheme) the(More)
We find a new class of metastable de Sitter solutions in compactifications of six-dimensional supergravity motivated by type IIB or heterotic string vacua. Two Fayet-Iliopoulos terms of a local U(1) symmetry are generated by magnetic flux and by the Green-Schwarz term canceling the gauge anomalies, respectively. The interplay between the induced D term, the(More)
