从SU(2)观点看D(2,1;a)超共形力学中的耦合

Couplings in D(2,1;a) superconformal mechanics from the SU(2) perspective

Anton Galajinsky

摘要:

从R-对称子群SU(2)的角度重新考虑了一维D(2,1;a)中最一般的N=4超共形群的动力学实现.证明了R-对称子代数在相空间中的任何实现都可以推广到对应于D(2,1;a)的李超代数的表示.构造了任意数目的(1,4,3)和(0,4,4)型超多重态与(3,4,1)或(4,4,0)型超多重态的耦合. D(2,1; a)考虑了四维和五维极端Reissner-Nordstrom-AdS-dS黑洞视界附近超粒子传播的超共形力学。参数a与宇宙学常数有关。

英文摘要:

Dynamical realizations of the most general N=4 superconformal group in one dimension D(2,1;a) are reconsidered from the perspective of the R-symmetry subgroup SU(2). It is shown that any realization of the R-symmetry subalgebra in some phase space can be extended to a representation of the Lie superalgebra corresponding to D(2,1;a). Novel couplings of arbitrary number of supermultiplets of the type (1,4,3) and (0,4,4) with a single supermultiplet of either the type (3,4,1), or (4,4,0) are constructed. D(2,1;a) superconformal mechanics describing superparticles propagating near the horizon of the extreme Reissner-Nordstrom-AdS-dS black hole in four and five dimensions is considered. The parameter a is linked to the cosmological constant.
