Spectroscopy of q 3 q ¯ 3 -States in Quark Model and Baryon-Antibaryon Enhancements
Abstract
We study the mass spectrum of the
q
3
q
¯
3
mesons both from the quark model with triquark correlations and from common quark model with colormagnetic interactions and with relative S-waves between quarks. Two cluster configurations
(
q
3
)−(
q
¯
3
)
and
(
q
2
q
¯
)−(q
q
¯
2
)
are considered. In the spectrum we find rather stable states which have the same quantum number with particle resonances which are corresponding to the
p
p
¯
enhancement,
p
Λ
¯
enhancement and
Λ
Λ
¯
enhancement with spin-
0
or
1
. This imply these enhancements are NOT experimental artifacts. The color-spin-flavor structures of
p

,
p

, and
Λ

enhancements are revealed. The existence of spin-
