    • Multistrange Meson-Baryon Dynamics and Resonance Generation 

      Khemchandani, K. P. [UNIFESP]; Martinez Torres, A.; Hosaka, A.; Nagahiro, H.; Navarra, F. S.; Nielsen, M. (Springer Wien, 2018)
      In this talk I review our recent studies on meson-baryon systems with strangeness -1 and -2. The motivation of our works is to find resonances generated as a consequence of coupled channel meson-baryon interactions. The ...
    • Understanding close-lying exotic charmonia states within QCD sum rules 

      Martinez Torres, A.; Khemchandani, K. P. [UNIFESP]; Dias, J. M.; Navarra, F. S.; Nielsen, M. (Elsevier Science Bv, 2017)
      Motivated by the experimental findings of some new exotic states decaying into channels like J/psi phi, we investigate the formation of resonances/bound states in the Ds*(D) over bars* system using QCD sum rules. To do ...
    • Why Xi(1690) and Xi(2120) are so narrow 

      Khemchandani, K. P. [UNIFESP]; Martinez Torres, A.; Hosaka, A.; Nagahiro, H.; Navarra, F. S.; Nielsen, M. (Amer Physical Soc, 2018)
      The Xi baryons are expected to be naturally narrower as compared to their nonstrange and strange counterparts since they have only one light quark and, thus, their decay involves producing either a light meson and doubly ...
