Determination of the strong coupling constant from the inclusive jet cross section in ppbar collisions at sqrt(s)=1.96 TeV

D0 Collaboration, V. M. Abazov

We determine the strong coupling constant alphas and its energy dependence from the pT dependence of the inclusive jet cross section in ppbar collisions at sqrt(s)=1.96 TeV. The st…

Relative K-stability of extremal metrics

Jacopo Stoppa, Gábor Székelyhidi

We show that if a polarised manifold admits an extremal metric then it is K-polystable relative to a maximal torus of automorphisms.

G parity boundary conditions and Delta I = 1/2, K to pi pi decays

Changhoan Kim, Norman H. Christ

The use of G-parity boundary conditions to compute Delta I = 1/2, K to pi pi decays is reviewed and a method to consistently treat both the pions and kaon in full QCD proposed. Thi…
