60. Heavy Quarkonium Production in pNRQCD

Dr Hee Sok Chung (Technical University of Munich)

Potential NRQCD (pNRQCD) effective field theory provides expressions for decay
rates and production cross sections of strongly coupled heavy quarkonia in
terms of quarkonium wavefunctions and universal gluon field correlators. This
brings in a reduction of the number of nonperturbative unknowns, and improves
the predictive power of the nonrelativistic effective field theory approach to
heavy...

25. Exotic hadrons in Λb → J/Ψ ϕ Λ decay

We study the weak decay of the $\Lambda_b$ baryon into $J/\psi\ \phi\ \Lambda$ and the possibility of formation of exotic hadrons via final state interaction in in all three final two-body channels.

In the $J/\psi \, \phi$ invariant mass spectrum we study the interplay between the $X(4140)$ and the $X(4160)$ resonances. Particularly for the $X(4160)$ resonance we use a theoretical model...
