作为Yang-Mills的二重复制的二重场论

Double Field Theory as the Double Copy of Yang-Mills

Felipe Diaz-Jaramillo, Olaf Hohm, Jan Plefka

摘要:

我们证明了双场论起源于Yang-Mills理论的色-运动学双拷贝。本文给出了二次和三次杨-米尔斯作用量的精确双拷贝公式,从而得到了对偶不变子已被积分的双场论作用量。更准确地说,在二次阶时,这产生了规范不变的二重场论,而在三次阶时,它产生了三次二重场论作用量,其规范条件源于弦场论中的西格尔规范。

英文摘要:

We show that double field theory arises from the color-kinematic double copy of Yang-Mills theory. A precise double copy prescription for the Yang-Mills action at quadratic and cubic order is provided that yields the double field theory action in which the duality invariant dilaton has been integrated out. More precisely, at quadratic order this yields the gauge invariant double field theory, while at cubic order it yields the cubic double field theory action subject to a gauge condition that originates from Siegel gauge in string field theory.
