AdS/CFT Correspondence的k弦的量子展宽

Quantum Broadening of k-Strings from the AdS/CFT Correspondence

Adi Armoni, Jefferson M. Ridgway

摘要:

我们研究了k弦的量子展宽。我们将Luscher、Munster和Weisz的一个旧结果推广到k弦的情况,使用规范/引力对应。当基本QCD弦被k弦的束缚态所取代时,束缚态可以用包裹的D膜来描述。我们用D-膜探针计算了几种AdS/CFT背景下k-弦(包裹D-膜)的宽度,普遍地发现ω_k^2 = 1 /(2πσ_k)log R/r .

英文摘要:

We study the quantum broadening (width) of k-strings. We generalise an old result by Luscher, Munster and Weisz to the case of a k-string, by using the gauge/gravity correspondence. When the fundamental QCD-string is replaced by a bound state of k strings, the bound state is better described by a wrapped D-brane. We calculate the width of the k-string (the wrapped D-brane) in several AdS/CFT backgrounds by using a D-brane probe and find universally that omega_k ^2 = 1 / (2πσ_k) log R/r .
