We consider the generalized hydrodynamics including recently introduced diffusion term for an initially inhomogeneous state in Lieb-Liniger model. construct a general solution to linearized equation terms of eigenstates evolution operator and study two prototypical classes initial states: delocalized localized spatially. exhibit some features resulting dynamics, among them, we highlight difference between ballistic diffusive evolution. The first one governs spatial scrambling, second,...

We test the AdS/CFT correspondence in case of a d=4 N=2 SCFT by comparing chiral anomalies which are order N 't Hooft large limit. These include corrections 1/N to conformal anomaly, thus testing beyond extreme The field theory reproduced terms 7-brane effective action bulk.

The aim of this paper is to discuss phenomenological consequences a particular unification model (Z_3 model) inspired by F-theory. most distinctive feature variety (cosmologically feasible) options for the NLSP and NNLSP, beyond usually considered benchmark scenarios.

We discuss a specific model of extended GMSB type in which 5bar component one messenger vector pair is treated as an extra flavour. FCNC effects related to the superpotential couplings between and i-th family MSSM matter, h_i, are analysed. find that strongest limit, h_1h_2<10^{-3}, emerges from constraints on RR slepton contribution radiative muon decay. The results agreement with simple models hierarchical Yukawa interactions.

Perturbative approach to two-dimensional gravity and supergravity is considered. One-loop renormalization of the central charge SL(2, R) Kac-Moody algebra calculated perturbatively by functional integration explicit calculations Feynman diagrams. Also wavefunction anomalous dimensions in presence are calculated.

We consider two simple examples of multi-instanton configurations in type II four-dimensional superstring compactifications. The first one involves O(1) and U(1) D2-instantons embedded [Formula: see text] geometry with SU(4) gauge symmetry coming from D6-branes the second is related to quiver theory orientifolded orbifold conifold containing fractional D (-1)-instantons D3-branes. additional zero modes instantons which appear at intersection points are lifted through interactions stemming...

We propose a GUT model in which visible matter and messengers are treated unified way what unavoidably leads to messenger-matter mixed Yukawa interactions. Influence of this mixing on the fermion masses weak angles is discussed.

In this Letter we consider U(1)A-gauged Polonyi model with two spurions coupled to a twisted closed string modulus. This offers consistent setup for metastable SUSY breakdown which allows moduli stabilization and naturally leads gauge or hybrid gauge/gravitational mediation mechanism. Due the presence of second spurion one can arrange solution μ Bμ problems in version modified Giudice–Masiero mechanism, works both limit pure mixed regime mediation.

Abstract We derive thermodynamic (TBA) and general hydrodynamic (GHD) equations corrected by virtual processes for integrable QFT on large but finite size space circle. Obtained TBA’s are solved numerically the sinh-Gordon model. Complicated Euler scale GHD expanded explicitly small occupation ratio of quasiparticles. The spectrum velocities linear approximation to is calculated.

We propose a string theory model which explains several features of two-dimensional Yang-Mills theory. Folds are suppressed. This in turn leads to the empty flat target spaces. The Nambu-Goto action appears usual way. naturally splits into two (chiral) sectors: orientation preserving maps and reversing maps. Moreover, it has straightforward extension three- four-dimensional space-times.

Various one-loop corrections to the four-graviton interaction in type-II superstring theory and heterotic string are sorted out some of them explicitly calculated. In particular, leading correction for \ensuremath{\alpha}'\ensuremath{\rightarrow}0 from amplitude is obtained. Also nonleading nonanalytic discussed their correspondence supergravity diagrams used classification.

We investigate a particular version of the Peccei-Quinn (PQ) NMSSM characterized by an economical and rigidly hierarchical flavor structure based on flavored gauge mediation some considerations inspired string theory GUTs. In this way we can express Lagrangian PQ through very few parameters. The obtained model is studied numerically confronted with most relevant phenomenological constraints. show that typical spectra are for part too heavy to be significantly probed at LHC, but regions...
