Three-Loop Effect in r.m.s and Charge Radii of Heavy Flavored Mesons in a QCD Potential Model
We make an analysis of r.m.s. and charge radii of heavy flavored mesons introducing the three-loop correction to the static potential \(V(r)=-\frac{4\alpha _s}{3r}+br\). Considering linear as parent and Coulomb as perturbation, the first order wave function is used to study the corresponding correction in coordinate space. The wave function is then used to study the r.m.s. and charge radii of heavy flavored mesons. The computed results are then compared with the data available in literature. The results show significant improvements compared to our earlier works.
期刊介绍:
International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
