The vertex in QCD Sum Rules: form factors and coupling constant

A. Cerqueira, B. Osório Rodrigues, M. E. Bracco +1

In this work we study the meson vertex using the QCD sum rules. We compute the three point correlation functions for the three cases of different off-shell mesons. The fo…

QCD Sum Rules Approach to the and States

Raphael M. Albuquerque, Jorgivan M. Dias, K. P. Khemchandani +4

In the past decade, due to the experimental observation of many charmonium-like states, there has been a revival of hadron spectroscopy. In particular, the experimental observation…

A QCD sum rules calculation of the and form factors and strong coupling constants

B. Osório Rodrigues, M. E. Bracco, C. M. Zanetti

We use the QCD sum rules for the three point correlation functions to compute the strong coupling constants of the meson vertices and . We consider pertu…

X, Y and Z States

M. Nielsen, R. M. Albuquerque, J. M. Dias +4

Many new states in the charmonium mass region were recently discovered by BaBar, Belle, CLEO-c, CDF, D0, BESIII, LHCb and CMS Collaborations. We use the QCD Sum Rule approach to st…

A QCD sum rule calculation of the decay width

J. M. Dias, K. P. Khemchandani, A. Martínez Torres +2

To understand the nature of the , recently observed in the mass spectrum of the system by the D0 Collaboration, we have investigated, in a previous work, a…

A QCD sum rule study for a charged bottom-strange scalar meson

C. M. Zanetti, M. Nielsen, K. P. Khemchandani

Using the QCD sum rule approach we investigate the possible four-quark structure for the new observed narrow structure (D0). We use a diquak-antidiquark scalar curre…
