The nonperturbative multi-gluons interaction is one of the
unique features of the strong interaction. Exotic hadrons, such as
glueballs and gluonic-excitation of hadrons are examples of where the
gluonic degrees of freedom could directly appear in the hadron spectrum.
An alternative approach to survey the multi-gluons interaction is to
study the t-channel diagrams in hadron-production reactions. The
phi-meson photoproduction off of nucleon offers a clean way to access
the gluon-rich interactions in the t-channel diagrams since quark
exchanges between phi-meson and nucleon are suppressed by the OZI rule.
In this talk, resent experimental studies on the phi-N interaction in
photoproduction reactions with CLAS at Jefferson laboratory are presented. |
