Annihilation *
We give perturbative predictions for the distribution of the C-parameter event shape variable in e + e − annihilation, including resummation of large logarithms in the two-jet (small-C) region, matched to next-to-leading order results. We also estimate the leading non-perturbative power correction and make a preliminary comparison with experimental data.
متن کاملLocal Annihilation Method and Some Stiff Problems
In this article, a new scheme inspired from collocation method is presented for numerical solution of stiff initial-value problems and Fredholm integral equations of the first kind based on the derivatives of residual function. Then, the error analysis of this method is investigated by presenting an error bound. Numerical comparisons indicate that the presented method yields accur...
متن کامل-annihilation Event
The collimation C of a hadronic event in the e + e −-annihilation is defined as the average of cos θ, C =< cos θ >, where θ is the angle of each hadron measured from the thrust axis, and the average is over all the hadrons produced in an event. It is an infrared-stable event-shape parameter. 1−C, the difference between the unity and the average collimation at a given energy, is proportional to ...
متن کاملAnnihilation mechanisms
This paper develops an ontologically rich explanation of the inner mechanics of the annihilation process, starting from a non-local hidden-variable (NLHV) design. This explains the process in terms of the handedness of matter and antimatter, the interaction of the electron and antielectron as they approach, the collapse of their discrete force structures and their reformation into photon struct...
متن کاملMist&-e Annihilation Games*
Graph games with an annihilation rule, as introduced by Conway, Fraenkel and Yesha, are studied under the midre play rule for progressively finite graphs that satisfy a condition on the reversibility of non-terminal Sprague-Grundy zeros to Spragu+Grundy ones. Two general theorems on the Spragu+Grundy zeros and ones are given, followed by two theorems characterizing the set of P-positions under ...
