Baryonium in Confining Gauge Theories

Kazuo Ghoroku, Masafumi Ishihara, Akihiro Nakamura +1

We show a new class of embedding solutions of D5 brane, which wraps on $S^{5}$ in the AdS $_{5} \times S^{5}$ space-time and contains fundamental strings as U(1) flux to form a baryon ve…

Baryons with D5 Brane Vertex and k-Quarks

Kazuo Ghoroku, Masafumi Ishihara

We study baryons in SU(N) gauge theories, according to the gauge/string correspondence based on IIB string theory. The D5 brane, in which $N$ fundamental strings are dissolved as a…

High temperature expansion in supersymmetric matrix quantum mechanics

Naoyuki Kawahara, Jun Nishimura, Shingo Takeuchi

We formulate the high temperature expansion in supersymmetric matrix quantum mechanics with 4, 8 and 16 supercharges. The models can be obtained by dimensionally reducing N=1 U(N)…

D3/D7 holographic Gauge theory and Chemical potential

Kazuo Ghoroku, Masafumi Ishihara, Akihiro Nakamura

N=2 supersymmetric Yang-Mills theory with flavor hypermultiplets at finite temperature and in the dS $_{4}$ are studied for finite quark number density ( $n_{b}$ ) by a dual supergravit…

Phase structure of matrix quantum mechanics at finite temperature

Naoyuki Kawahara, Jun Nishimura, Shingo Takeuchi

We study matrix quantum mechanics at finite temperature by Monte Carlo simulation. The model is obtained by dimensionally reducing 10d U(N) pure Yang-Mills theory to 1d. Following…

Flavor quarks in AdS4 and gauge/gravity correspondence

Kazuo Ghoroku, Masafumi Ishihara, Akihiro Nakamura

The non-perturbative properties of the gauge theories in the AdS $_{4}$ are studied in the dual supergravity by including light flavor quarks, which are introduced by a D7 brane emb…
