A Precise Determination from the R-improved QCD Static Energy
Jose M. Mena-Valle, Vicent Mateu, Pablo G. Ortega
The strong coupling is determined with high precision from fits to lattice QCD simulations on the static energy. Our theoretical setup relies on R-improving the three-loop f…

Exploring the Efimov effect in the system
Pablo G. Ortega
The emergence of the Efimov effect in the system is explored under the assumption that the heavy partner of the exists as a molecule with $(I)J^P=(0…
