We formulate the Hopf algebra underlying the su(2|2) worldsheet S-matrix of the AdS 5 × S 5 string in the AdS/CFT correspondence. For this we extend the previous construction in the su(1|2) subsector due to Janik to the full algebra by specifying the action of the coproduct and the antipode on the remaining generators. The nontriviality of the coproduct is determined by length-changing effects ...

We study heavy-light baryon resonances with quantum numbers JP = 12 − in terms of the non-linear chiral SU(3) Lagrangian. Within the χ−BS(3) approach a parameterfree leading order prediction is obtained for the scattering of Goldstone bosons off heavy-light baryon resonances with JP = 12 + . The three states Λc1(2593),Λc0(2880) and Ξc1(2790) discovered by the CLEO collaboration are recovered. W...

Haraz-Ghareh Su is one of the seven sub-basins of the Caspian basin, located on the southern shores of the Caspian Sea, and as such, is in danger of water crisis due to absence of proper systematic policy and strategy. In this study, the pressure factors on the Haraz-Ghareh Su water resources were identified using DPSIR model. Then, the pressure parameters on the freshwater resources in the Cas...

The N = 1 self-dual supergravity has SL(2,C) symmetry . This symmetry results in SU(2) charges as the angular-momentum. As in the nonsupersymmetric self-dual gravity, the currents are also of their potentials and are therefore identically conserved. The charges are generally invariant and gauge covariant under local SU(2) transforms approaching to be rigid at spatial infinity. The Poisson brack...

Each of these examples turns out to be a surface in R 2 or C 2 = R 2 . The trivial group is a single point and the general linear group is an open subset of R 2 or C 2 . The unitary group U(1) is the unit circle S in C = R, and the special orthogonal group SO(2) turns out to be the same thing even though it lives in R. The special unitary group SU(2) is the three dimensional sphere S (even thou...

We explore the relationship between the SU(2) sector of a general integrable field theory and the all-loop guess for the anomalous dimensions of SU(2) operators in N = 4 super Yang-Mills theory. We demonstrate that the SU(2) structure of a nested Bethe ansatz alone reproduces much of the all-loop guess without depending on the details of the particular field theory. We speculate on the implicat...

Treatment of the radiated ®eld from a toroid antenna as two A ®elds in resonance or a U ®eld, and the toroid as a U ®eld radiator, results in the prediction of (i) omnidirectional radiation patterns (with small indentations at the poles), and (ii) periodic resonances in the driving conditions. These predictions have been con®rmed experimentally, giving validity to the fundamental nature of this...
