摘要:

利用无限体积中散射矩阵与周期盒中两粒子谱之间的关系,通过对小π质量2mpi <mrho时Nf =2类动力学三叶草费米子的模拟,计算了ρ介子的质量和宽度.

英文摘要:

Using established relations between the scattering matrix in infinite volume and the two-particle spectrum in a periodic box, we compute the mass and width of the rho meson from simulations of N_f=2 flavors of dynamical clover fermions at small pion masses 2 m_pi < m_rho.
