Calculating Masses of Pentaquarks Composed of Baryons and Mesons

Abstract EN

We consider an exotic baryon (pentaquark) as a bound state of two-body systems composed of a baryon (nucleon) and a meson.

We used a baryon-meson picture to reduce a complicated five-body problem to simple two-body problems.

The homogeneous Lippmann-Schwinger integral equation is solved in configuration space by using one-pion exchange potential.

We calculate the masses of pentaquarks θ c ( u u d d c ¯ ) and θ b ( u u d d b ¯ ) .
