摘要: 我们计画研究AdS/QCD 对偶理论中一般的D 膜超引力解得到的模型— Dp-Dq
膜模型,即在Dp 膜的时空背景下,研究在Dq 膜上的开弦激发态。在Dp-Dq 膜
模型中,D 膜的空间维数p 和q 被看成两个独立的理论参数。同时我们还将进
一步引入红外截断,这会导致背景时空度规中弯曲因数(warp factor)的改变,
此外dilaton 场也会随红外截断而改变。这些改变也提供了更多的理论参数。
这样我们就可以用实验资料来拟合这些理论参数,找出与实验符合的最好的理
论图像,从而更系统、更有效地研究现象学中的问题。我们希望在此模型的基
础上研究强子物理中的一些问题。包括强子谱的Regge 行为、手征对称性破缺
与π介子质量、胶球的能谱以及与其他粒子的相互作用。
We plan to study a type of models of AdS/QCD duality theory with the
gerenal D-branes supergravity backgrounds — Dp-Dq branes models, i.e.
we study the open string states on the probe Dq-branes in the space-time
background of Dp-branes. In these Dp-Dq brane models, the space
dimensions p and q are considered as two independent tjepretoca;
parameters. Furthermore, we are going to introduce a IR cutoff, which
modifies the warp factor of the space-time backgrounds, as well as the
dilaton fields. These modifications create some more theoretical
parameters. Therefore, we can fix these parameters by comparing them with
the experimental data to obtain the best fitting theoretical picture.
Finally, we are going to use the best fitting theoretical picture we got
to systematically study some interesting problems in the phenomenology
physics, such as the Regge behavior of the hadrons spectrum, the
spontaneously chiral symmetry breaking and pion mass, the glueball
spectrum and their interactions with other particles, etc.
