Isospin symmetry breaking and scaling observed in pion production in p+d reactions
Abstract A stack of annular detectors made of high purity germanium was used to measure p+d→3 He+π0 and p+d→3 H+π+ differential and total cross sections at...

Partition functions of NAHE-based free fermionic string models
Abstract The heterotic string free fermionic formulation produced a large class of three generation models, with an underlying SO(10) GUT symmetry which is broken directly at the string level by Wilson lines. A common subset of boundary condition...

Field identifications for interacting bosonic models in N=2 superconformal field theory
Abstract We study a family of interacting bosonic representations of the N=2 superconformal algebra. These models can be tensored with a conjugate theory to give the free theory. We explain how to use free fields to study interacting fields and...

Fermion doubling and Berenstein–Maldacena–Nastase correspondence
Abstract We show that the string bit model suffers from doubling in the fermionic sector. The doubling leads to strong violation of supersymmetry in the limit N→∞. Since there is an exact correspondence between string bits and the algebra of BMN...

Atmospheric neutrino mixing and b–τ unification
Abstract Extrapolating the τ and b masses in the MSSM tends to give for their ratio at the GUT scale a number around 1.2, for most viable values tanβ, rather than the minimal SU(5) prediction of 1. We suggest that this may be due to large...

Subleading light-cone distribution functions in the decays Λb→Xsγ and Λb→Xuℓν̄ℓ
Abstract In this Letter we investigate the subleading twist corrections to the photon energy spectrum in the decay Λ b →X s ...

Effects of chiral restoration on the behaviour of the Polyakov loop at strong coupling
Abstract We discuss the relation between the Polyakov loop and the chiral order parameter at finite temperature. For that purpose we analyse an effective model proposed by Gocksch and Ogilvie, which is constructed by the double expansion of strong...

Re-examination of electroweak symmetry breaking in supersymmetry and implications for light superpartners
Abstract We examine arguments that could avoid light superpartners as an implication of supersymmetric radiative electroweak symmetry breaking. We argue that, from the point of view of string theory and standard approaches to generating the μ term,...

Finite-temperature regularization
Abstract We present a non-perturbative regularization scheme for Quantum Field Theories which amounts to an embedding of the original unregularized theory into a spacetime with an extra compactified dimension of length L∼Λ −1...

Non-Abelian horizontal symmetry and anomalous U(1) symmetry for the supersymmetric flavor problem
Abstract It is shown that using non-Abelian horizontal gauge symmetry and anomalous U(1) A symmetry in grand unified theories (GUTs), realistic quark and lepton mass matrices including large neutrino...

Search for a narrow state at 1.9 GeV in 3π+2π−π0 exclusive events in n̄p annihilation
Abstract No evidence has been found for a narrow state at 1.911 GeV, recently reported by E687, in an analysis of the 3π +2π − π 0 exclusive events produced in ...

Higgsino and wino dark matter from Q-ball decay in Affleck–Dine baryogenesis
Abstract We claim that the higgsino-like and wino-like neutralinos can be good dark matter candidates if they are produced by the late time decay of Q-ball, which is generally formed in Affleck–Dine baryogenesis. The late time decays of the Q-balls...

The one loop effective action of QED for a general class of electric fields
Abstract We compute the effective action of QED at one loop order for an electric field which points in the ẑ direction and depends arbitrarily upon the light cone time coordinate, x+=(x0+x3)/ 2 ...

Neutrinoless double beta decay can constrain neutrino dark matter
Abstract We examine how constraints can be placed on the neutrino component of dark matter by an accurate measurement of neutrinoless double beta (0νββ) decay and the solar oscillation amplitude. We comment on the alleged evidence for 0νββ decay. ...

Bubbles in anti-de Sitter space
Abstract We explore the bubble spacetimes which can be obtained from double analytic continuations of static and rotating black holes in anti-de Sitter space. In particular, we find that rotating black holes with elliptic horizon lead to bubble...

Chiral Lagrangian from gauge invariant, nonlocal, dynamical quark model
Abstract Parameters of Gasser–Leutwyler chiral Lagrangian are proved saturated by dynamical quark self energy Σ(k 2) in a gauge invariant, nonlocal, dynamical quark model.

Laser photons acquire circular polarization by interacting with a Dirac or Majorana neutrino beam
Abstract It is shown that for the reason of neutrinos being left-handed and their gauge-couplings being parity-violated, linearly polarized photons acquire their circular polarization by interacting with neutrinos. Calculating the ratio of linear...

Biased retro-proportional navigation law for interception of high-speed targets with angular constraint
Abstract A new guidance law, called biased retro proportional navigation (BRPN), is proposed. The guidance law is designed to intercept high-speed targets with angular constraint, which can be used for ballistic target interception. BRPN guidance...
