Regge trajectories for the triply heavy triquarks
Abstract We attempt to apply the Regge trajectory approach to the triply heavy triquarks $$((QQ')\bar{Q}^{\prime \prime })$$ ( ( Q Q ′ ) Q ¯ ″ ) $$(Q,\,Q', Q^{\prime \prime }=b,\,c).$$ ( Q , Q ′ , Q ″ = b , c ) . We present the triquark Regge trajectory relations, and then employ them to c...

| Summary: | Abstract We attempt to apply the Regge trajectory approach to the triply heavy triquarks $$((QQ')\bar{Q}^{\prime \prime })$$ ( ( Q Q ′ ) Q ¯ ″ ) $$(Q,\,Q', Q^{\prime \prime }=b,\,c).$$ ( Q , Q ′ , Q ″ = b , c ) . We present the triquark Regge trajectory relations, and then employ them to crudely estimate the spectra of the triquarks $$((cc)\bar{c}),$$ ( ( c c ) c ¯ ) , $$((cc)\bar{b}),$$ ( ( c c ) b ¯ ) , $$((bc)\bar{c}),$$ ( ( b c ) c ¯ ) , $$((bc)\bar{b}),$$ ( ( b c ) b ¯ ) , $$((bb)\bar{c}),$$ ( ( b b ) c ¯ ) , and $$((bb)\bar{b}).$$ ( ( b b ) b ¯ ) . The $$\lambda $$ λ -trajectories and the $$\rho $$ ρ -trajectories are discussed. The triquark Regge trajectory becomes a new and very simple approach for estimating the spectra of triquarks. Moreover, the spin-averaged masses of the ground states of pentaquarks $$(\bar{c}(cc))(cc),$$ ( c ¯ ( c c ) ) ( c c ) , $$(\bar{b}(cc))(cc)$$ ( b ¯ ( c c ) ) ( c c ) and $$(\bar{c}(bb))(cc)$$ ( c ¯ ( b b ) ) ( c c ) are estimated, which are consistent with other theoretical predictions. |
