NN, N-DELTA COUPLINGS AND THE QUARK-MODEL
Quark model vector axis vector

2014/12/23
We examine mass-corrected SU(6) symmetry predictions in the quark model relating vector, axial-vector, and strong NN and NΔ couplings, and demonstrate that the experimental NΔ value is significantly h...

2014/12/19
We calculate chiral corrections to the semileptonic vector and axial quark coupling constants using a manifestly Lorentz covariant chiral quark approach up to order O(p4) in the two- and three-flavor ...
Equivalence Principle Violations and Couplings of a Light Dilaton
Exchange of light coupling inverse cubic root atoms scalar coupling parameterized

2014/12/18
We consider possible violations of the equivalence principle through the exchange of a light “dilaton-like” scalar field. Using recent work on the quark-mass dependence of nuclear binding, we find tha...

2010/12/23
The use of a running coupling constant in renormalizable theories is well known, but the implementation of this idea for effective field theories with a dimensional coupling constant is in general le...

2010/10/27
We report an unexpected systematic degeneracy between di erent multiplets in an inversion symmetric system of two coupled Gaudin models with homogeneous couplings, as occurring for example in the cont...
