PT symmetry in relativistic quantum mechanics
PT symmetry relativistic quantum mechanics High Energy Physics - Theory
2011/9/29
Abstract: In nonrelativistic quantum mechanics and in relativistic quantum field theory, time t is a parameter and thus the time-reversal operator T does not actually reverse the sign of t. However, i...

Nucleon strange quark content from two-flavor lattice QCD with exact chiral symmetry
Nucleon strange quark content two-flavor lattice QCD
2011/1/6
Strange quark content of the nucleon is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginsparg-Wilson relati...

Chiral Symmetry Restoration in Holographic Noncommutative QCD
Chiral Symmetry Holographic Noncommutative QCD
2010/12/23
We consider the noncommutative deformation of the Sakai-Sugimoto model at finite temperature and finite baryon chemical potential. The influence of the space noncommutativity on the flavor dynamics of...
Chiral symmetry breaking revisited: the gap equation with lattice ingredients
Chiral symmetry breaking revisited the gap equation lattice ingredients
2011/1/7
We study chiral symmetry breaking in QCD, using as ingredients in the quark gap equation recent lattice results for the gluon and ghost propagators. The Ansatz employed for the quark-gluon vertex is p...

FV-type action AdS(5) mixed-symmetry fields
2010/12/24
We formulate Fradkin-Vasiliev type theory of massless higher spin fields in AdS(5). The corresponding action functional describes cubic order approximation to gravitational interactions of bosonic mi...
Open mirror symmetry for Pfaffian Calabi-Yau 3-folds

2010/12/23
We investigate the open mirror symmetry of certain non-complete intersection Calabi- Yau 3-folds, so called pfaffian Calabi-Yau. We perform the prediction of the number of disk invariants of several ...
Symmetry Breaking Phase Transitions in ABJM Theory with a Finite U(1) Chemical Potential
ABJM Theory Finite U(1) Chemical Potential
2010/12/24
We consider the U(1) charged sector of ABJM theory at finite temperature, which corresponds to the Reissner-Nordstrom AdS black hole in the dual type IIA supergravity description. Including back-react...

Invariance of the AdS_4 x CP^3 superstring under D=3 N=6 superconformal symmetry is discussed in the sector described by the OSp(4|6)/(SO(1,3) x U(3)) supercoset sigma-model action presented in the c...

2011/1/7
Recent experimental data have revealed large mirror energy differences (MED) between high-spin states in the mirror nuclei 67Se and 67As, the heaviest pair where MED have been determined so far. The M...
Warped Electroweak Breaking Without Custodial Symmetry
Warped Electroweak Breaking Custodial Symmetry
2010/12/27
We propose an alternative to the introduction of an extra gauge (custodial) symmetry to suppress the contribution of KK modes to the T parameter in warped theories of electroweak breaking. The mechan...
