论文摘要
答案是在涉及DILATON的隐藏量表对称性中发现的,在核物质的较强核相关性中出现。有人建议,相同的机制起源于较高的声速的较高密度,在巨大的紧凑型星星的核心中融合到所谓的````伪符合形式的声速''$ v_s^2/c^2/c^2 \ 1/3 $。大约1/3 $。预测也可能导致$ g_a $在核培养基中的真正``基本的重新规范化''。
The answer is found in the way the hidden scale symmetry involving a dilaton emerges in strong nuclear correlations in nuclear matter. It is suggested that the same mechanism is at the origin at higher densities of the sound speed converging in the core of massive compact stars to what could be called ``pseudo-conformal sound speed" $v_s^2/c^2\approx 1/3$. A precision measurement of the superallowed Gamow-Teller transitions in the doubly magic nucleus $^{100}$Sn is suggested to confirm or falsify this prediction. It could also lead to the possible determination of genuine ``fundamental renormalization" of $g_A$ in nuclear medium.
