Re-analysis of data on a0(1450) and a0(980)
D. V. Bugg
Four sets of data determining parameters of a0(1450) and a0(980) are re-analysed. These are Crystal Barrel data for pbar-p annihilation at rest to eta-pizero-pizero in (i) liquid h…
How Resonances can synchronise with Thresholds
D. V. Bugg
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 con…
Experimental disagreements with Extended Unitarity
D. V. Bugg
In production processes, e.g. J/Psi -> omega-pi-pi or pbar-p -> 3pi, the sigma and fo(980) overlap in the same partial wave. The conjecture of Extended Unitarity (EU) states that t…
A Study in Depth of f0(1370)
D. V. Bugg
Claims have been made that f0(1370) does not exist. The five primary sets of data requiring its existence are refitted. Major dispersive effects due to the opening of the 4pi thres…
The pi-pi mass spectrum in Y(4260) -> pi-pi-J/psi
D. V. Bugg
Three ways of fitting the pi-pi mass spectrum in Y(4260) decays are studied. Data presented recently by Belle cannot be fitted by the pi-pi S-wave intensity for elastic scattering.…
