共形自对偶域

Conformal self-dual fields

R. R. Metsaev

摘要:

研究了大于或等于4的偶数维平坦时空中的共形自对偶场。普通衍生制定这样的领域的发展。得到了具有常规动力学项的规范不变拉格朗日量和相应的规范变换。规范对称性是通过涉及施图克尔伯格场来实现的。得到了整体共形对称的实现。找到了光锥规范拉格朗日量,并证明了光锥规范在计算共形自对偶场壳自由度中的应用。

英文摘要:

Conformal self-dual fields in flat space-time of even dimension greater than or equal to four are studied. Ordinary-derivative formulation of such fields is developed. Gauge invariant Lagrangian with conventional kinetic terms and corresponding gauge transformations are obtained. Gauge symmetries are realized by involving the Stueckelberg fields. Realization of global conformal symmetries is obtained. Light-cone gauge Lagrangian is found. Also, we demonstrate use of the light-cone gauge for counting of on-shell degrees of freedom of the conformal self-dual fields.
