Scalar-isoscalar states, gravitational form factors, and dimension-2 condensates in a large-Nc Regge approach
Scalar-isoscalar states gravitational form factors dimension-2 condensates
2011/1/7
Scalar-isoscalar states are analyzed within the large-Nc Regge approach. We find that the lightest f0(600) scalar-isoscalar state fits very well into the pattern of the radial Regge trajectory. We con...

In 16O and 40Ca an isoscalar, low-energy dipole transition (IS-LED) exhausting approximately 4% of the isoscalar dipole (ISD) energy-weighted sum rule is experimentally known, but conspicuously absent...
