2+1味全QCD中的轻标量介子

Light scalar mesons in 2+1 flavor full QCD

摘要:

本文研究了a_0和K_0^* 轻标量介子的2+1味全QCD。特别注意的是,拟合激发态,眼睛朝向确定是否散射状态被揭示。最终的目标是观察动力学夸克如何影响早先用重叠费米子进行的猝灭研究所描绘的图景,即最低的$\bar{q}q$等矢量标量态是a_0(1450),而不是a_0(980)。

英文摘要:

We study the a_0 and K_0^* light scalar mesons in 2+1 flavor full QCD. Particular attention is paid to fitting excited states, with an eye toward determining whether scattering states are revealed. An ultimate goal will be to see how dynamical quarks affect the picture outlined with an earlier quenched study using overlap fermions, namely, that it is the a_0(1450), not the a_0(980), which is the lowest $\bar{q}q$ isovector scalar state.
