Recent studies of the Q dependence of ep scattering in the large x region and in the Q range: 1 ≤ Q ≤ 30 Gev, confirm the validity of the phenomenon of quark-hadron duality the similarity of the deep inelastic (parton) and resonance (hadron) spectra for values of the invariant mass, W 2 ≥ 2.4 GeV. At lower values of W , duality is found to be significantly violated by an amount that cannot be p...

We develope the analogue of S-duality for linearized gravity in (3+1)-dimensions. Our basic idea is to consider the self-dual (anti-self-dual) curvature tensor for linearized gravity in the context of the Macdowell-Mansouri formalism. We find that the strong-weak coupling duality for linearized gravity is an exact symmetry and implies small-large duality for the cosmological constant. Pacs numb...

The occurrence of the Bloom-Gilman duality in the nucleon structure function is investigated by analyzing the Q2-behavior of low-order moments, both including and excluding the contribution arising from the nucleon elastic peak. The Natchmann definition of the moments has been adopted in order to cancel out target-mass effects. It is shown that the onset of the Bloom-Gilman duality occurs aroun...

Starting with a given generalized boson algebra U〈q〉(h(1)) known as the bosonized version of the quantum super-Hopf Uq(osp(1|2)) algebra, we employ the Hopf duality arguments to provide the dually conjugate function algebra Fun〈q〉(H(1)). Both the Hopf algebras being finitely generated, we produce a closed form expression of the universal T matrix that caps the duality and generalizes the famili...

We study a new process, which we call ASEP(q, j), where particles move asymmetrically on a one-dimensional integer lattice with a bias determined by q ∈ (0, 1) and where at most 2 j ∈ N particles per site are allowed. The process is constructed from a (2 j + 1)-dimensional representation of a quantum Hamiltonian with Uq(sl2) invariance by applying a suitable ground-state transformation. After s...

Abstract Using gauge/gravity duality, we investigate the string breaking and dissolution of two heavy quarks coupled to a light quark at finite temperature. It is found that three configurations QQq exist with increase in separation distance for confined phase. Furthermore, occurs ( T 0.1\; {\rm{GeV}} ) decay mode {Q Q q} \rightarrow q q+Q \bar{q}} . In ...

We give a short introduction to and a partial review of the work on the calculation of Wilson loops and Q ¯ Q-potentials via the conjectured AdS/CFT duality. Included is a discussion of the relative weight of the stringy correction to the target space background versus the correction by the quantum fluctuations of the string world sheet. Abstract. We give a short introduction to and a partial r...
