线性约束超引力下的地球质量

Glueball Masses from Linearly Confining Supergravity

Girma Hailu

摘要:

利用我们提出的纯N=1四维SU(N)规范理论在红外大N极限下的双超引力理论产生了0++胶球的质量谱,胶球状态用惠特克函数表示。光谱是离散的,其根给出质量的函数被写入。质量比与理论参数无关,与最近的非超对称大N格点量子色动力学数据比较,最低三个态的一致性在5%以内。

英文摘要:

Mass spectrum of 0++ glueballs is produced using a dual supergravity theory we proposed for pure N=1 SU(N) gauge theory in four dimensions in the large N limit in the IR. The glueball states are expressed in terms of Whittaker functions. The spectrum is discrete and a function whose roots give the masses is written. The ratios of the masses are independent of the parameters of the theory and comparison to recent non-supersymmetric large N lattice QCD data available for the lowest three states shows agreement to within five percent.
