Distributed Spin in a String Picture of Hadrons
Akio Sugamoto
In a string picture of hadrons, spins are distributed over the whole configuration of string. According to this picture, spin of hadron is discussed in a dual gravity theory of QCD…
Pentaquark Baryons in String Theory -- Talk at Pentaquark 04
M. Bando, T. Kugo, A. Sugamoto +1
Pentaquark baryons and are studied in the dual gravity theory of QCD in which simple mass formulae of pentaquarks are derived in the Maldacena prototype model for…
Dynamical Origin of Duality between Gauge Theory and Gravity
Akiko Noguchi, Akio Sugamoto
Dynamical origin of duality between gauge theory and gravity is studied using the dual transformation and the formation of graviton as a collective excitation of dual gauge bosons.…
Singular Gauge Transformation in Non-Commutative U(2) Gauge Theory
Yuko Kobashi, Akio Sugamoto
A method developed by Polychronakos to study singular gauge transformations in 1+2 dimensional non-commutative Chern-Simons gauge theory is generalized from U(1) group to U(2) grou…
An Attempt to Study Pentaquark Baryons in String Theory
Akio SUGAMOTO
An attempt to study recently observed Pentaquark baryons is performed in the dual string theory of QCD. Mass formulae for Pentaquark baryons are naively estimated in the Maldacena'…
'TeV Gamma-ray Crisis' and an Anisotropic Space Model
Gi-Chol Cho, Jun-ichi Kamoshita, Mariko Matsunaga +2
To solve the `TeV gamma crisis', we examine a model whose one spatial direction is discretized at a high energy scale. Assuming the standard extra-galactic IR photon distribution,…
