摘要

回顾了在激发强子中手性与 $U(1)_A$ 对称性恢复的情况。讨论了这些恢复与高度激发强子半经典范程之间的联系。 presented a solvable confining field-theoretical toy model that exhibits chiral restoration. Implications of the string description of the highly excited hadrons that suggests an additional dynamical symmetry of the spectra on the top of $U(2)_L \times U(2)_R$ are presented.
