It is conventionally argued that dark matter (DM) has a non-baryonic nature, but if we assume that DM was frozen out before primordial nucleosynthesis and could not significantly impact primordial abundances this argument may be evaded. Then a hypothetical SU (3) flavor-singlet, highly symmetric, deeply bound neutral scalar hexaquark S = uuddss , which due to its features has escaped from experimental detection so far, may be considered as a candidate for a baryonic DM. In the present work we calculate the mass and coupling constant of the scalar six-quark particle S by means of the QCD sum rule method. Our predictions for its mass are ##IMG## [http://ej.iop.org/images/0954-3899/47/9/095001/gab9a0eieqn1.gif] {${m}_{\mathrm{S}}=118{0}_{-26}^{+40} \mathrm{M}\mathrm{e}\mathrm{V}$} ( m s = 95 MeV) and ##IMG## [http://ej.iop.org/images...] {${\tilde {m}}_{\mathrm{S}}=123{9}_{-28}^{+42} \mathrm{M}\mathrm{e}\mathrm{V}$}

标量六夸克uuddss:暗物质的候选者?

传统上认为暗物质(DM)具有非重离子性质,但是如果我们假设DM在原始核合成之前被冻结,并且不会显着影响原始丰度,则可以逃避这一论点。然后,假设的SU(3)风味单,高度对称的,深度结合的中性标量六夸克S = uuddss,由于其功能目前尚未从实验检测中逃脱,因此可以考虑作为重粒DM的候选对象。在目前的工作中,我们通过QCD和规则方法计算了标量六夸克粒子S的质量和耦合常数。我们对其质量的预测是## IMG ## [http://ej.iop.org/images/0954-3899/47/9/095001/gab9a0eieqn1.gif] {$ {m} _ {\ mathrm {S} } = 118 {0} _ {-26} ^ {+ 40} \ mathrm {M} \ mathrm {e} \ mathrm {V} $}(ms = 95 MeV)和## IMG ## [http:// ej.iop.org/images ...
