Description
One of the most known result of the string theory consists in the
idea that some strongly coupled gauge theories may have a dual
description in terms of a higher dimensional weakly coupled
gravitational theory --- the so-called AdS/CFT correspondence or
gauge/gravity correspondence. The attempts to apply this idea to
the real QCD are often referred to as "holographic QCD" or
"AdS/QCD approach". One of directions in this field is to start
from the real QCD and guess a tentative dual higher dimensional
weakly coupled field model following the principles of
gauge/gravity correspondence. The ensuing phenomenology can be
then developed and compared with experimental data and with
various theoretical results. Such a bottom-up holographic approach
turned out to be unexpectedly successful in many cases. In the
given talk, we make a short review of the bottom-up
holographic approach to QCD and some of its applications.
