有限体积下的n-玻色子能量和三玻色子相互作用

n-Boson Energies at Finite Volume and Three-Boson Interactions

Silas R. Beane, William Detmold, Martin J. Savage

摘要:

我们计算了在L边的周期性空间体积中具有短程排斥相互作用的n个全同玻色子的基态能量与体积的关系,直到并包括1/L^6阶项。有了这个结果,用格点量子色动力学计算三个或更多π介子的基态能量,就可以系统地提取体积膨胀中这个量级的三π介子相互作用。

英文摘要:

We calculate the volume dependence of the ground-state energy of n identical bosons with short-range repulsive interactions in a periodic spatial volume of side L, up to and including terms of order 1/L^6. With this result, Lattice QCD calculations of the ground-state energies of three or more pions will allow for a systematic extraction of the three-pion interaction at this order in the volume expansion.
