Doubly heavy Baryons from QCD Spectral Sum Rules

R. M. Albuquerque, S. Narison

We consider the ratios of doubly heavy baryon masses using Double Ratios of Sum Rules (DRSR), which are more accurate than the usual simple ratios used for getting hadron masses. O…

Mass-splittings of doubly heavy baryons in QCD

R. M. Albuquerque, S. Narison

We consider (for the first time) the ratios of doubly heavy baryon masses (spin 3/2 over spin 1/2 and SU(3) mass-splittings) using double ratios of sum rules (DRSR), which are more…

Can the X(4350) narrow structure be a $1^{-+}$ exotic state?

Raphael M. Albuquerque, Jorgivan M. Dias, Marina Nielsen

Using the QCD sum rules we test if the new narrow structure, the X(4350) recently observed by the Belle Collaboration, can be described as a $J^{P C} = 1^{-+}$ exotic $D_{s}^{*} D_{s 0}^{*}$ …
