大质量高自旋场的无限超多重态

An infinite supermultiplet of massive higher-spin fields

Xavier Bekaert, Michel Rausch de Traubenberg, Mauricio Valenzuela

摘要:

从现代的角度重新审视了马约拉纳写的无限分量相对论波动方程的表象理论。一方面,该方程的无质量解被证明形成了具有张量中心荷的超庞加莱代数的超多重态,它也可以作为有质量解的无限自旋极限而得到。另一方面,马约拉纳方程推广到任何时空维度和任意Regge轨迹。受这些结果的启发,我们在四维空间中构造了一个质量相等的所有自旋的质量场的无限超多重态,并证明了它带有正交辛群OSp(1)的不可约表示|4)和具有张量荷的superPoincare群。

英文摘要:

The representation theory underlying the infinite-component relativistic wave equation written by Majorana is revisited from a modern perspective. On the one hand, the massless solutions of this equation are shown to form a supermultiplet of the superPoincare algebra with tensorial central charges; it can also be obtained as the infinite spin limit of massive solutions. On the other hand, the Majorana equation is generalized for any space-time dimension and for arbitrary Regge trajectories. Inspired from these results, an infinite supermultiplet of massive fields of all spins and of equal mass is constructed in four dimensions and proved to carry an irreducible representation of the orthosymplectic group OSp(1|4) and of the superPoincare group with tensorial charges.
