Phantom and non-phantom dark energy: The cosmological relevance of non-locally corrected gravity
Abstract In this Letter we have investigated the cosmological dynamics of non-locally corrected gravity involving a function of the inverse d'Alembertian of the Ricci scalar, f ( ...

Parameterizing the lepton mixing matrix in terms of deviations from tri-bimaximal mixing
Abstract We propose a parametrization of the lepton mixing matrix in terms of an expansion in powers of the deviations of the reactor, solar and atmospheric mixing angles from their tri-bimaximal values. We show that unitarity triangles and neutrino ...

Some properties of meta-stable supersymmetry-breaking vacua in Wess–Zumino models
Abstract As a contribution to the current efforts to understand supersymmetry-breaking by meta-stable vacua, we study general properties of supersymmetry-breaking vacua in Wess–Zumino models: we show that tree-level degeneracy is generic, explore...

A deformed relativity with the quantum ℏ
Abstract Quantum relativity as a generalized, or rather deformed, version of Einstein relativity may offer a new framework to think about the structure of space–time at the true microscopic/quantum level. The approach typically gives some picture of ...

Cosmology with light axions from technicolor
Abstract We consider cosmological consequences of the spontaneous breaking of a global symmetry that is anomalous under technicolor interactions, leading to the emergence of a light axion-like particle. Avoiding overclosure of the universe by such...

Electroweak corrections to Higgs production through ZZ fusion at the linear collider
Abstract We present the full O ( α ) electroweak radiative corrections to e ...

Schnabl's solution and boundary states in open string field theory
Abstract We discuss that Schnabl's solution is an off-shell extension of the boundary state describing a D-brane in the closed string sector. It gives the physical meaning of the gauge-invariant overlaps for the solution in our previous paper and...

Radiative seesaw: a case for split supersymmetry
Abstract We revive Witten's mechanism for the radiative seesaw induced neutrino masses in SO(10) grand unified theory. We propose its extension to charged fermion masses as a possible cure for wrong tree level mass relations. We offer two simple...

Constraints on gravitational scaling dimensions from non-local effective field equations
Abstract Quantum corrections to the classical field equations, induced by a scale dependent gravitational constant, are analyzed in the case of the static isotropic metric. The requirement of general covariance for the resulting non-local effective...

Effective Lagrangian at cubic order in electromagnetic fields and vacuum birefringence
Abstract The effective Lagrangian of electromagnetic fields at the cubic order in field strength is considered. This generalized Lagrangian is motivated by electrodynamics on non-commutative spaces. We find the canonical and symmetrical...

Casimir effect confronts cosmological constant
Abstract It has been speculated that the zero-point energy of the vacuum, regularized due to the existence of a suitable ultraviolet cut-off scale, could be the source of the non-vanishing cosmological constant that is driving the present...

Torus amplitudes in minimal Liouville gravity and matrix models
Abstract We evaluate one-point correlation numbers on the torus in the Liouville theory coupled to the conformal matter M ( 2 , ...

Unitarisation and black-disk limit at the LHC in the presence of a hard pomeron
Abstract Recent models of soft diffraction include a hard pomeron pole besides the usual soft term. Such models violate the black-disk limit around Tevatron energies, so that they need to be supplemented by a unitarisation scheme. Two standard...

CP violation from scatterings with gauge bosons in leptogenesis
Abstract We present an explicit computation of the CP asymmetry in scattering processes involving the heavy right-handed neutrinos of the type I seesaw framework and the Standard Model gauge bosons. Compared to CP violation in two-body decays and in ...

Lorentz violation from the Higgs portal
Abstract We study bounds and signatures of models where the Higgs doublet has an inhomogeneous mass or vacuum expectation value, being coupled to a hidden sector that breaks Lorentz invariance. This physics is best described by a low-energy...

Timelike and spacelike nucleon electromagnetic form factors beyond relativistic constituent quark models
Abstract For the first time, a phenomenological analysis of the experimental electromagnetic form factors of the nucleon, both in the timelike and spacelike regions, is performed by taking into account the effects of nonvalence components in the...
