1-- and 0++ heavy four-quark and molecule states in QCD
R. M. Albuquerque, F. Fanomezana, S. Narison +1
We estimate the masses of the 1^{--} heavy four-quark and molecule states by combining exponential Laplace (LSR) and finite energy (FESR) sum rules known perturbatively to lowest o…
1^{-+} light exotic mesons in QCD
Stephan Narison
We systematically re-examine the extraction of the masses and couplings of the 1^{-+} hybrid, four-quark and molecule mesons from QCD spectral sum rules (QSSR). To NLO for the pert…
SU(3) mass-splittings of heavy-baryons in QCD
R. M. Albuquerque, S. Narison, M. Nielsen
We extract directly (for the first time) the charmed (C=1) and bottom (B=-1) heavy-baryons (spin 1/2 and 3/2) mass-splittings due to SU(3) breaking using double ratios of QCD spect…
|V_{cd}|, |V_{cs}| and f_{D_s} from (semi) leptonic -decays : signals of New Physics ?
Stephan Narison
We confront the recent improved measurements of the D_{(s)} (semi) leptonic decays with lattice QCD (LQCD) with n_f=3 flavours and QCD spectral sum rules (QSSR) predictions. D\toμν…
V-A hadronic tau decays : a laboratory for the QCD vacuum
Stephan Narison
ALEPH/OPAL data on the V-A spectral functions from hadronic tau decays are used in connection with a set of Laplace transform sum rules (LSR) for fixing the size of the QCD vacuum…
