Initial States: IR and Collinear Divergences
The standard approach to the infra-red problem is to use the Bloch-Nordsieck trick to handle soft divergences and the Lee-Nauenberg (LN) theorem for collinear singularities. We show that this is inconsistent in the presence of massless initial particles. Furthermore, we show that using the LN theorem with such initial states introduces a non-convergent infinite series of diagrams at any fixed o...
متن کاملInfrared Divergences from Soft and Collinear Gauge Bosons
To compare with experiment it is vital that theoretical predictions are finite. Beyond leading order in perturbation theory many processes contain infrared divergences. It is often argued that these singularities are eliminated at the level of the inclusive cross-section [1,2]. During this talk I will show that the infrared divergences are still poorly understood. I also expose some questionabl...
متن کاملCancellation of soft and collinear divergences in noncommutative QED
In this paper, we investigate the behavior of non-commutative IR divergences and will also discuss their cancellation in the physical cross sections. The commutative IR (soft) divergences existing in the non-planar diagrams will be examined in order to prove an all order cancellation of these divergences using the Weinberg’s method. In noncommutative QED, collinear divergences due to triple pho...
متن کاملCollinear Divergences at One-loop Order for External Particles in a Heat-bath
In hard interactions between external particles incident on a heatbath, we show that large logarithms are generated when a radiated or absorbed gauge boson is collinear with the initial fermion momentum. These logarithms can be absorbed into process independent splitting/absorption probabilities. Unlike the zero-temperature case, however, they depend explicitly on the temperature and the scale ...
متن کاملInvestigation of non-collinear spin states with scanning tunneling microscopy.
Most ferromagnetic and antiferromagnetic substances show a simple collinear arrangement of the local spins. Under certain circumstances, however, the spin configuration is non-collinear. Scanning tunneling microscopy with its potential atomic resolution is an ideal tool for investigating these complex spin structures. Non-collinearity can be due to topological frustration of the exchange intera...
