Model - independent confirmation of the Z ( 4430 ) [ superscript - ] state
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Model-independent confirmation of the Zð4430Þ − state R. Aaij et al. The decay B 0 → ψð2SÞK þ π − is analyzed using 3 fb −1 of pp collision data collected with the LHCb detector. A model-independent description of the ψð2SÞπ mass spectrum is obtained, using as input the Kπ mass...
متن کاملHow Resonances can synchronise with Thresholds
The mechanism by which a threshold may capture a resonance is examined. It involves a threshold cusp interfering constructively with either or both (i) a resonance produced via confinement, (ii) attractive tand u-channel exchanges. The f0(980), X(3872) and Z(4430) are studied in detail. The f0(980) provides a valuable model of the locking mechanism. The X(3872) is too narrow to be fitted by a c...

Measurements of the branching fractions of → ± ∓ B K K * s and π → ± ∓ B K* s decays are performed using a data sample corresponding to − 1.0 fb 1 of protonproton collision data collected with the LHCb detector at a centre-of-mass energy of 7 TeV, where the ± K* mesons are reconstructed in the π± KS final state. The first observation of the → ± ∓ B K K * s decay and the first evidence for the π...
متن کاملDynamics study of Z+(4430) and X(3872) in molecular picture
In this talk, we review our recent work about the dynamical studies of Z+(4430) and X(3872). Z+(4430) can not be explained as a D1D ∗ or D1D∗ molecular state only considering one pion exchange potential without the cutoff, which needs to be confirmed by introducing sigma exchange potential and adding the cutoff in the effective potential. One also excludes the possibility of X(3872) as a DD∗ mo...
