Threshold cusps and triangle singularities in hadronic reactions

FK Guo, XH Liu, S Sakai - Progress in Particle and Nuclear Physics, 2020 - Elsevier
The spectrum of hadrons is the manifestation of color confinement of quantum

We consider the D¯(*) Σ c (*) states, together with J/ψ N and other coupled channels, and
take an interaction consistent with heavy quark spin symmetry, with the dynamical input …

LHCb pentaquark as a molecular state

L Roca, J Nieves, E Oset - Physical Review D, 2015 - APS
We perform a theoretical analysis of the Λ b→ J/ψ Kp reaction from where a recent LHCb
experiment extracts a Λ (1405) contribution in the Kp spectrum close to threshold and two …
