Z+(4430) as a cusp in D*(2010)Dbar_1(2420)
D.V. Bugg (Queen Mary, University of London, UK)
TL;DR
This paper proposes that the Z+(4430) particle is best understood as a threshold cusp phenomenon arising from the D*(2010)Dbar_1(2420) system, offering a new interpretation of its nature.
Contribution
It introduces a novel explanation for Z+(4430) as a cusp effect at the D*(2010)Dbar_1(2420) threshold, differing from previous resonance-based models.
Findings
Z+(4430) can be explained as a threshold cusp.
The cusp occurs at the D*(2010)Dbar_1(2420) threshold.
This interpretation aligns with observed properties of Z+(4430).
Abstract
The Z^+(4430) observed by Belle is explained naturally as a threshold cusp in the D*(2010)Dbar_1(2420) system.
