Photoproduction of isolated photons, inclusively and with a jet, at HERA
Abstract The photoproduction of isolated photons, both inclusive and together with a jet, has been measured with the ZEUS detector at HERA using an integrated luminosity of 374 ...

Ginzburg–Landau phase diagram of QCD near chiral critical point – chiral defect lattice and solitonic pion condensate
Abstract We investigate the influence of the isospin asymmetry on the phase structure of quark matter near the chiral critical point systematically using a generalized version of Ginzburg–Landau approach. The effect has proven to be so profound that ...

Implications of a light radion on the RG evolution of Higgs self coupling in the Randall–Sundrum model
Abstract In this Letter we determine how the beta function of the Higgs self coupling λ at one loop order is modified by a light stabilized radion in the Randall–Sundrum model. We then use the modified beta function to derive a lower bound on the...

New effects in gauge theory from pp-wave superstrings
Abstract It has recently been observed that IIB string theory in the pp-wave background can be used to calculate certain quantities, such as the dimensions of BMN operators, as exact functions of the effective coupling λ′=λ/J 2. ...

Calculation of four-point correlation function of logarithmic conformal field theory using AdS/CFT correspondence
Abstract We use the correspondence between scalar field theory on AdS and induced conformal field theory on its boundary to calculate correlation functions of logarithmic conformal field theory in arbitrary dimensions. Our calculations utilize the...

Effects of universal extra dimensions on B0–B0 mixing
Abstract We study contributions coming to Δm B from one or more universal extra dimensions (UED) in which all the Standard Model fields can propagate. In the model with a single...

Time evolution of the fission-decay width under the influence of dissipation
Abstract Different analytical approximations to the time-dependent fission-decay width used to extract the influence of dissipation on the fission process are critically examined. Calculations with a new, highly realistic analytical approximation to ...

Limits on the neutrino magnetic moment from the MUNU experiment
Abstract The MUNU experiment was carried out at the Bugey nuclear power reactor. The aim was the study of ν ̄ ee− ...

Renormalization group equations in gauge theories with multiple U(1) groups
Abstract Two-loop renormalization group equations in gauge theories with multiple U(1) groups are presented. Instead of normalizing the Abelian gauge fields in canonical forms, we retain kinetic-mixing terms and treat the mixing coefficients as free ...

Supersymmetric D2–anti-D2 strings
Abstract We consider the flat supersymmetric D2 and anti-D2 system, which follows from ordinary noncommutative D2–anti-D2 branes by turning on an appropriate worldvolume electric field describing dissolved fundamental strings. We study the strings...

Charged kaon condensation in high density quark matter
Abstract We show that at asymptotically high densities the “color-flavor-locked+neutral kaon condensate” phase of QCD develops a charged kaon condensate through the Coleman–Weinberg mechanism. At densities achievable in neutron stars a charged kaon...

Description of supernova data in conformal cosmology without cosmological constant
Abstract We consider cosmological consequences of a conformal-invariant formulation of Einstein's General Relativity where instead of the scale factor of the spatial metrics in the action functional a massless scalar (dilaton) field occurs which...

Electroweak precision data, light sleptons and stability of the SUSY scalar potential
Abstract The light slepton–sneutrino scenario with nonuniversal scalar masses at the GUT scale is preferred by the electroweak precision data. Though a universal soft breaking mass at or below the Plank scale can produce the required nonuniversality ...

Fast low-energy halo-to-halo transfers between Sun–planet systems
Abstract In this paper, the problem of fast low-energy halo-to-halo transfers between Sun–planet systems is discussed under ephemeris constraints. According to the structure of an invariant manifold, employing an invariant manifold and planetary...

Integrable interpolations: From exact CFTs to non-Abelian T-duals
Abstract We derive two new classes of integrable theories interpolating between exact CFT WZW or gauged WZW models and non-Abelian T-duals of principal chiral models or geometric coset models. They are naturally constructed by gauging symmetries of...

Microscopic self-consistent study of neon halos with resonant contributions
Abstract Recent reaction measurements have been interpreted as evidence of a halo structure in the exotic neutron-rich isotopes 29,31Ne. While theoretical studies of 31Ne generally agree on its halo nature, they differ significantly in their...
