Open spin chain and open spinning string
Abstract In this Letter, we study the open spinning strings and their SYM duals. A new class of folded open spinning strings is found. At planar one-loop level in SYM, by solving the thermodynamic limit of the Bethe ansatz equations for an...

Reprint of: Assessment of a frequency-domain linearised Euler solver for turbofan aft radiation predictions and comparison with measurements
Abstract This paper presents a frequency-domain computational aeroacoustics tool for predicting aft noise radiation through turbofan ducts and jets and its application to two realistic engine exhaust configurations which have been experimentally...

T–μ phase diagram of the chiral quark model from a large flavor number expansion
Abstract The chiral phase boundary of strong matter is determined in the T–μ plane from the chiral quark model, applying a non-perturbatively renormalised treatment, involving chains of pion-bubbles and 1-loop fermion contributions. In the absence...

Top quark spin correlations at the Tevatron and the LHC
Abstract Spin correlations of top quarks produced in hadron collisions have not been observed experimentally with large significance. In this Letter, we propose a new variable that may enable demonstration of the existence of spin correlations with ...

Finite temperature pion vector form factors in chiral perturbation theory
Abstract We discuss the thermal behaviour of the pion vector form factors and calculate them in one-loop chiral perturbation theory. The perturbative result is used to analyze the T-dependent electromagnetic pion charge radius, obtaining a rough...

Inclusive cross-sections for jet production in nucleus–nucleus collisions in the perturbative QCD pomeron model
Abstract Inclusive cross-sections for gluon jet production are studied numerically in the perturbative QCD pomeron model for central collisions of identical nuclei at high energies. Two forms for the inclusive cross-sections, with and without...

Delta-N formalism for the evolution of the curvature perturbations in generalized multi-field inflation
Abstract The δN formalism is considered to calculate the evolution of the curvature perturbation in generalized multi-field inflation models. The result is consistent with the usual calculation of the standard kinetic term. For the calculation of...

Multigravity from a discrete extra dimension
Abstract Multigravity theories are constructed from the discretization of the extra dimension of five-dimensional gravity. Using an ADM decomposition, the discretization is performed while maintaining the four-dimensional diffeomorphism invariance...

Neutrino magnetic moments and photo-disintegration of deuterium
Abstract Neutrinos with non-zero magnetic moments can dissociate deuterium nuclei by a photon exchange, in addition to the weak neutral current process. We calculate the neutrino magnetic moment induced photo-dissociation cross section of deuterium...

Beyond the Higgs boson at the Tevatron: Detecting gluinos from Yukawa-unified SUSY
Abstract Simple SUSY GUT models based on the gauge group SO ( 10 ) require t – ...

Brane–antibrane solution and SUSY effective potential in five-dimensional Mirabelli–Peskin model
Abstract A localized configuration is found in the 5D bulk-boundary theory on an S 1/Z 2 orbifold model of Mirabelli and Peskin. A bulk scalar and the extra (fifth) component of the bulk vector constitute...

Parity doubling in the meson spectrum
Abstract A simple argument for the restoration of parity symmetry high in the hadron spectrum is presented. The restoration scale is estimated to be 2.5 GeV. This in turn implies that typical quark model phenomenology such as scalar confinement or...

Conformal symmetry and the Standard Model
Abstract We re-examine the question of radiative symmetry breaking in the Standard Model in the presence of right-chiral neutrinos and a minimally enlarged scalar sector. We demonstrate that, with these extra ingredients, the hypothesis of...

Quark distributions in a medium
Abstract We derive the formal expressions needed to discuss the change of the twist-two parton distribution functions when a hadron is placed in a medium with relativistic scalar and vector mean fields.

Quantum cooling evaporation process in regular black holes
Abstract We investigate a universal behavior of thermodynamics and evaporation process for the regular black holes. We observe an important point where the temperature is maximum, the heat capacity is changed from negative infinity to positive...

Radiative viscosity of neutron stars
Abstract We study non-linear effects of radiative viscosity of npe matter in neutron stars for both direct Urca process and modified Urca process, and find that non-linear effects will decrease the ratio of radiative viscosity to bulk viscosity from ...

The neutrino response of low-density neutron matter from the virial expansion
Abstract We generalize our virial approach to study spin-polarized neutron matter and the consistent neutrino response at low densities. In the long-wavelength limit, the virial expansion makes model-independent predictions for the density and spin...

Model independent method for determination of the DIS structure of free neutron
Abstract We present a model independent procedure for extracting deep-inelastic structure function of “free” neutron from the electron–deuteron scattering with protons produced in the target fragmentation region of the reaction. This procedure is...
