T. Ledwig, J. Martin-Camalich, V. Pascalutsa, and M. Vanderhaeghen
An expansion of the electromagnetic form factors of the nucleon and Delta(1232) in small momentum transfer and pion mass is performed in a manifestly covariant EFT framework consistent with chiral symmetry and analyticity. We present the expressions for the nucleon and Delta(1232) electromagnetic fo ... [Phys. Rev. D 85, 034013 ] published .

Fast fits for lattice QCD correlators

K. Hornbostel, G. P. Lepage, C. T. H. Davies, R. J. Dowdall, H. Na et al. HPQCD collaboration
We illustrate a technique for fitting lattice QCD correlators to sums of exponentials that is significantly faster than traditional fitting methods1040 times faster for the realistic examples we present. Our examples are drawn from a recent analysis of the Upsilon spectrum, and another recent analys ... [Phys. Rev. D 85, 031504 ] published .

Jet physics from static charges in AdS space

Yang-Ting Chien, Matthew D. Schwartz, David Simmons-Duffin, and Iain W. Stewart
Soft interactions with high-energy jets are explored in radial coordinates which exploit the approximately conformal behavior of perturbative gauge theories. In these coordinates, the jets, approximated by Wilson lines, become static charges in Euclidean AdS. The anomalous dimension of the correspon ... [Phys. Rev. D 85, 045010 ] published .

Equation of state of a quasiparticle model at finite chemical potential and quark star

Ya-Lan Tian, Yan Yan, Hua Li, Xin-Lian Luo, and Hong-Shi Zong
In this paper, we employ the equation of state (EOS) of the quasiparticle model proposed in A. M. Zhao et al., Mod. Phys. Lett. A 25, 47 (2010)] which incorporates the effect of vacuum negative pressure to study the properties of quark stars. In our model the EOS has the correct behavior required by ... [Phys. Rev.

Light dark matter and the electroweak phase transition in the NMSSM

Marcela Carena, Nausheen R. Shah, and Carlos E. M. Wagner
We analyze the stability of the vacuum and the electroweak phase transition in the NMSSM close to the Peccei-Quinn symmetry limit. This limit contains light dark matter (DM) particles with a mass significantly smaller than the weak scale and also light CP-even and CP-odd Higgs bosons. Such light par ... [Phys. Rev.

Twinlike models for self-dual Maxwell-Higgs theories

D. Bazeia, E. da Hora, and R. Menezes
In this work we present a theoretical framework that allows for the existence of coherent twinlike models in the context of self-dual Maxwell-Higgs theories. We verify the consistency of this framework by using it to develop some twinlike self-dual Maxwell-Higgs models. We use a combination of theor ... [Phys. Rev. D 85, 045005 ] published .

We consider two-dimensional [script N]=(0,2) sigma models with the CP(1) target space. A minimal model of this type has one left-handed fermion. Nonminimal extensions contain, in addition, N right-handed fermions. Our task is to derive expressions for the beta functions valid to all orders. To this ... [Phys. Rev. D 85, 045004 ] published .

Kinematics of deep inelastic scattering in leading order of the covariant approach

The behavior of the Landau gauge gluon and ghost propagators is studied in pure SU(3) gauge theory at nonzero temperature on the lattice. We concentrate on the momentum range (0.6, 2.0) GeV. For the longitudinal as well as for the transverse component of the gluon propagator we extract the continuum ... [Phys. Rev. D 85, 034501 ] published .

Precise predictions for Z-boson +4 jet production at hadron colliders

We present the cross section for production of a Z boson in association with four jets at the Large Hadron Collider, at next-to-leading order in the QCD coupling. When the Z decays to neutrinos, this process is a key irreducible background to many searches for new physics. Its computation has been m ... [Phys. Rev. D 85, 031501 ] published .

Possibility of generating leading-order gaugino masses in a direct gauge mediation scenario

Tirtha Sankar Ray
Generating gaugino masses at the leading order has typically been difficult in direct/semidirect gauge mediated supersymmetry breaking models.
