$d^\ast(2380)$ was observed by WASA-at-COSY collaborations in the nuclear reaction recently. Its particularly narrow width may indicate the new QCD-allowed hadronic structure. To further confirm the existence of this peculiar particle in a totally different kind of reaction, we study the opportunity for searching $\bar{d}^\ast$ in the $\Upsilon(nS)$ (with n=1, 2, 3) decay. As a phenomenological study, our framework is based on SU(3) chiral quark model. By virtue of the unitarity of $S$-matrix…

Recently, a study has shown that the Bose Einstein Condensates formed by the $d^*$(2380) hexaquarks ($d^*$(2380)-BECs) can be thermally produced in the early universe and they are stable enough to be

The first exclusive and kinematically complete measurements of the most basic double-pionic fusion reaction pn-->dpi; {0}pi;{0} at beam energies of 1.03 and 1.35 GeV reveal the ABC effect to be a (pipi)_{I=L=0} channel phenomenon associated with both a resonancelike energy dependence in the integral cross section and the formation of a DeltaDelta system in the intermediate state.
