Baryonium Study in Heavy Baryon Chiral Perturbation Theory

Understand

To see whether heavy baryon and anti-baryon can form a bound state, the heavy baryonium, we study the interaction potential between them in terms of heavy baryon perturbation theory.

• The obtained potential is applied to calculate the heavy baryonium masses by solving Schr\"{o}dinger equation.
• We find it is true that the heavy baryonium may exist in a reasonable choice of input parameters.
• The uncertainties remaining in the potential and their influences on the heavy baryonium mass spectrum are discussed.
