The quintic interaction vertex in light-cone gravity
Abstract We consider pure gravity in light-cone gauge and derive the complete quintic interaction vertex. Up to quartic order, the Kawai–Lewellen–Tye (KLT) relations can be made manifest at the level of the Einstein–Hilbert Lagrangian. The quintic...

An interplay between static potential and Reggeon trajectory for QCD string
Abstract I consider two cases where QCD string is described by an effective theory of long strings: the static potential and meson scattering amplitudes in the Regge regime. I show how they can be solved in the mean-field approximation, justified by ...

Seesaw options for three neutrinos
Abstract The seesaw mechanism for three neutrinos is discussed, clarifying the situation where the seesaw texture results in three approximately zero mass eigenvalues. The true underlying mechanism is shown to be just the inverse (or linear) seesaw, ...

Possible signals of wino LSP at the Large Hadron Collider
Abstract We consider a class of anomaly-mediated supersymmetry breaking models where gauginos acquire masses mostly from anomaly mediation while masses of other superparticles are from Kähler interactions, which are as large as gravitino mass ...

Path integral formulation with deformed antibracket
Abstract We propose how to incorporate the Leites–Shchepochkina–Konstein–Tyutin deformed antibracket into the quantum field–antifield formalism.

Roles of isoscalar hyperons in probing the density dependence of the nuclear symmetry energy
Abstract The role of the isoscalar hyperon Λ in probing the density dependence of the nuclear symmetry energy is studied in multi-Λ hypernuclei, hyperon-rich matter and neutron stars in relativistic models. Relationships between the properties of...

Physical non-equivalence of the Jordan and Einstein frames
Abstract We show, considering a specific f ( R ) -gravity model, that the Jordan frame and the Einstein frame could be physically...

Updating algorithms with multi-step stochastic correction
Abstract Nested multi-step stochastic correction offers a possibility to improve updating algorithms for numerical simulations of lattice gauge theories with fermions. The corresponding generalisations of the two-step multi-boson (TSMB) algorithm as ...

Azimuthal asymmetry in unpolarized πN Drell–Yan process
Abstract Taking into account the effect of final-state interaction, we calculate the non-zero (naïve) T-odd transverse momentum dependent distribution h 1 ...

Scale invariance, unimodular gravity and dark energy
Abstract We demonstrate that the combination of the ideas of unimodular gravity, scale invariance, and the existence of an exactly massless dilaton leads to the evolution of the universe supported by present observations: inflation in the past,...

Gauge amplitude identities by on-shell recursion relation in S-matrix program
Abstract Using only the Britto–Cachazo–Feng–Witten (BCFW) on-shell recursion relation we prove color-order reversed relation, U ( 1 ) ...

A note on partition functions of Gepner model orientifolds
Abstract In this note we generalize the description of simple current extended Gepner model orientifolds as presented in hep-th/0401148 on the case of even levels and non-trivial dressings of the parity transformation. We provide a comprehensive...

Sphalerons, antisphalerons and vortex rings
Abstract We present new classical solutions of Weinberg–Salam theory in the limit of vanishing weak mixing angle. In these static axially symmetric solutions, the Higgs field vanishes either on isolated points on the symmetry axis, or on rings...

Possible theoretical limits on holographic quintessence from weak gravity conjecture
Abstract The holographic dark energy model is one of the important ways for dealing with the dark energy problems in the quantum gravity framework. In this model, the dimensionless parameter c plays an essential role in determining the evolution of...

Gauge invariance and vacuum energies of non-Abelian string-configurations
Abstract We improve on a method to compute the fermion contribution to the vacuum polarization energy of string-like configurations in a non-Abelian gauge theory. We establish the new method by numerically verifying the invariance under (a subset...

Gauge coupling unification in the Standard Model
Abstract The string landscape suggests that the supersymmetry breaking scale can be high, and then the simplest low energy effective theory is the Standard Model (SM). We show that gauge coupling unification can be achieved at about ...

Exact travelling wave solutions for some nonlinear partial differential equations
Abstract In this work, we construct explicit by the travelling wave solutions involving parameters of the Boussinesq and Benjamin–Ono equations by using a new approach, namely the ...
