Reflecting Magnon Bound States
Changrim Ahn, Dongsu Bak, Soo-Jong Rey
In N=4 super Yang-Mills spin chain, we compute reflection amplitudes of magnon bound-state off giant graviton. We first compute the reflection amplitude off Y=0 brane boundary and…
NLIE of Dirichlet sine-Gordon Model for Boundary Bound States
Changrim Ahn, Zoltan Bajnok, Laszlo Palla +1
We investigate boundary bound states of sine-Gordon model on the finite-size strip with Dirichlet boundary conditions. For the purpose we derive the nonlinear integral equation (NL…
The QCD spin chain S matrix
Changrim Ahn, Rafael I. Nepomechie, Junji Suzuki
Beisert et al. have identified an integrable SU(2,2) quantum spin chain which gives the one-loop anomalous dimensions of certain operators in large N QCD. We derive a set of nonlin…
Stringy Jacobi fields in Morse theory
Yong Seung Cho, Soon-Tae Hong
We consider the variation of the surface spanned by closed strings in a spacetime manifold. Using the Nambu-Goto string action, we induce the geodesic surface equation, the geodesi…
Probing extra dimensions with higher dimensional black hole analogues?
Xian-Hui Ge, Sung-Won Kim
We propose that extra dimensions might be detected with higher dimensional analogues of black holes. The usual 4-dimensional acoustic(sonic)black hole metric is extended to arbitra…
Measurement on the thermal neutron capture cross section of w-180
W. G. Kang, Y. D. Kim, J. I. Lee +3
We have measured the thermal neutron capture cross section for w-180 nucleus. There is only one previous data on this cross section with a value of 30 $^{+300%}_{-100%}$ barn. To c…
