Noncommutative Quantum Scattering in a Central Field
Stefano Bellucci, Armen Yeranyan
In this paper the problem of noncommutative elastic scattering in a central field is considered. General formulas for the differential cross-section for two cases are obtained. For…
Accelerator Tests of Crystal Undulators
V. M. Biryukov, A. G. Afonin, V. T. Baranov +22
A series of Silicon crystal undulator samples were produced based on the approach presented in PRL 90 (2003) 034801, with the periods of undulation from 0.1 mm to 1 mm, and the num…
Spin bits at two loops
S. Bellucci, P. -Y. Casteill, A. Marrani +1
We consider the Super Yang--Mills/spin system map to construct the SU(2) spin bit model at the level of two loops in Yang--Mills perturbation theory. The model describes a spin sys…
New insight into WDVV equation
S. Bellucci, A. V. Galajinsky, E. Latini
We show that Witten-Dijkgraaf-Verlinde-Verlinde equation underlies the construction of N=4 superconformal multi--particle mechanics in one dimension, including a N=4 superconformal…
On matrix models for anomalous dimensions of super Yang-Mills theory
Stefano Bellucci, Corneliu Sochichiu
We consider the matrix model approach to the anomalous dimension matrix in super Yang--Mills theory. We construct the path integral representation for the anomalous…
SL(2) spin chain and spinning strings on AdS_5xS^5
S. Bellucci, P. -Y. Casteill, J. F. Morales +1
We derive the coherent state representation of the integrable spin chain Hamiltonian with symmetry group SL(2,R). By passing to the continuum limit, we find a spin chain sigma mode…
