Γ agreement experimental value lap chiral perturbation theory the dispersion relation
2014/12/23
Agreement between the experimental value Γ(KS→γγ) and the number predicted via a one-loop chiral perturbation theory calculation has been cited as a success for the latter. On the other hand the one-l...

Low energy inflation models fermion
2014/12/23
In theories in which the parameters of the low energy theory are not unique, perhaps having different values in different domains of the universe as is possible in some inflationary models, the fermio...
Decay pi(0)->gamma gamma to next to leading order in chiral perturbation theory
Decay of amplitude induced mixing pure state low energy
2014/12/20
The π0→γγ decay width is analyzed within the combined framework of chiral perturbation theory and the 1/Nc expansion up to O(p6) and O(p4×1/Nc) in the decay amplitude. The η′ is explicitly included in...
