Quantum Corrections to the Gravitational Interaction of Massless Particles
Collinear Divergence Effective Field Theory General Relativity Infrared Divergence Massless Quantum Gravity
2014/11/20
Donoghue's effective field theory of quantum gravity is extended to include the interaction of massless particles. The collinear divergences which accompany massless particles are examined first in th...
Non-adiabatic transitions in a massless scalar field
Non-adiabatic transitions massless scalar field Mathematical Physics
2012/4/17
We consider the dynamics of a massless scalar field with time-dependent sources in the adiabatic limit. This is an example of an adiabatic problem without spectral gap. The main goal of our paper is t...
Extended supersymmetry in massless conformal higher spin theory
Extended supersymmetry massless conformal higher spin theory Mathematical Physics
2011/7/28
Abstract: We propose superfield equations in tensorial N-extended superspaces to describe the N=2,4,8 supersymmetric generalizations of free conformal higher spin theories. These can be obtained by qu...
We discuss the status of different determinations of alpha_s, motivating a precise and reliable computation from lattice QCD. In order to suppress perturbative errors, the non-perturbative computation...

Near Horizon Limits of Massless BTZ and Their CFT Duals
Near Horizon Limits Massless BTZ Their CFT Duals
2010/12/23
We consider the massless BTZ black hole and show that it is possible to take its "near horizon" limit in two distinct ways. The first one leads to a null self-dual orbifold of AdS3 and the second to a...
We discuss the status of different determinations of as, motivating a precise and reliable computation from lattice QCD. In order to suppress perturbative errors, the non-perturbative computation has ...
Multiloop calculations with Implicit Regularization in massless theories
Regularization Renormalization Multiloop calculations
2010/6/30
We establish a systematic way to calculate multiloop amplitudes of infrared safe massless models with Implicit Regularization (IR), with a direct cancelation of the fictitious mass introduced by the p...
Thermodynamic limit of particle-hole form factors in the massless XXZ Heisenberg chain
Thermodynamic limit particle-hole XXZ Heisenberg chain
2010/4/6
We study the thermodynamic limit of the particle-hole form factors of the XXZ Heisenberg chain in the massless regime. We show that, in this limit, such form factors decrease as an explicitly computed...
Gupta-Bleuler quantization for massive and massless free vector fields
vector fields quantization Gupta-Bleuler
2010/7/8
It is shown that the usual quantum field theory leads to an ultraviolet divergence in the vacuum energies and an infrared divergence in the two-point functions of the massive and massless vector field...
Massive and massless neutrinos on unbalanced seesaws

2009/7/31
The observation of neutrino oscillations requires new physics beyond the standard model (SM). A SM-like gauge theory with p lepton families can be extended by introducing q heavy right-handed Majoran...

Consistency of the Born Approximation for Aharonov-Bohm Scattering with Massless spin-1/2 Particles
Born Approximation Aharonov-Bohm Scattering Massless spin-1/2 Particles

The second order contribution for the relativistic scattering of massless spin-\frac{1}{2} particles from an infinitely long solenoid, in the context of covariant perturbation theory, is calculated an...
