| 英文摘要 | We reexamine whether z(+)(4430) could be a d(1)'-d* or d(1)-d* molecular state after considering both the pion and sigma meson exchange potentials and introducing the form factor to take into account the structure effect of the interaction vertex. our numerical analysis with matlab package matslise indicates the contribution from the sigma meson exchange is small for the d(1)'-d* system and significant for the d(1)-d* system. the s-wave d(1)-(d) over bar* molecular state with only j(p)=0(-) and d(1)'-d* molecular states with j(p)=0(-),1(-),2(-) may exist with reasonable parameters. one should investigate whether the broad width of d(1)' disfavors the possible formation of molecular states in the future. the bottom analog z(b) of z(+)(4430) has a larger binding energy, which may be searched at tevatron and lhc. experimental measurement of the quantum number of z(+)(4430) may help uncover its underlying structure. |
