Fully and Doubly-heavy four-quarks within QCD Laplace sum rule
R. M. Albuquerque, S. Narison, A. Rabemananjara +1
We present a review of our results for the masses and couplings of the scalar fully heavy four-quarks and tetraquarks states from QCD…
Doubly hidden molecules and tetraquarks states from QCD at NLO
R. M. Albuquerque, S. Narison, A. Rabemananjara +2
Motivated by the LHCb-group discovery of exotic hadrons in the range (6.2 6.9) GeV, we present new results for the masses and couplings of fully heavy $(\bar{Q}Q)(Q…
Doubly-hidden scalar heavy molecules and tetraquarks states from QCD at NLO
R. M. Albuquerque, S. Narison, A. Rabemananjara +2
Alerted by the recent LHCb discovery of exotic hadrons in the range (6.2 -- 6.9) GeV, we present new results for the doubly-hidden scalar heavy charm and beau…
XYZ -- spectra from QCD Laplace Sum Rules at Higher Orders
R. Albuquerque, S. Narison, A. Rabemananjara +2
We review our results in Refs.[1,2] for the masses and couplings of heavy-light DD(BB)-like molecules and (Qq)(Qq)-like four-quark states from relativistic QCD Laplace sum rules (L…
Scalar Meson Contributions to a_μfrom Hadronic Light-by-Light Scattering
M. Knecht, S. Narison, A. Rabemananjara +1
Using an effective σ/f_0(500) resonance, which describes the ππ-->ππand γγ-->ππscattering data, we evaluate its contribution and the ones of the other scalar mesons to the the hadr…
0+ and 1+ heavy-light exotic mesons at N2LO in the chiral limit
R. M Albuquerque, S. Narison, F. Fanomezana +3
We use QCD spectral sum rules (QSSR) and the factorization properties of molecule and four-quark currents to estimate the masses and couplings of the 0+ and 1+ molecules and four-q…
