Exchange Cross Sections for Hard Binaries
We present results on the exchange cross section for the interaction between a hard binary and a field of single stars, for arbitrary masses. The results are based partly on extensive numerical scattering experiments, and partly on analytic estimates of the mass-dependence of the cross section. They can be used to estimate the rate of exchange in an arbitrary mixture of masses, provided that th...
متن کاملCharge Exchange Cross Sections for the Io Plasma Torus
An impact parameter method for calculating cross sections as a function of incident ion energy is used in conjunction with an improved exchange energy formulation to update several of the charge exchange cross sections currently used in Io plasma torus modeling. New cross sections for S + + S 2 + • S 2 + + S + and Na + on neutral targets, useful in analyzing the fast Na jets observed at Io, are...
متن کاملBinary-single-star Scattering — Vii. Hard Binary Exchange Cross Sections for Arbitrary Mass Ratios: Numerical Results and Semi-analytic Fits
We present the first comprehensive fitting formula for exchange reactions of arbitrary mass ratios. In a comparison with numerical results, this expression is shown to be accurate in the hard binary limit to within 25% for most mass ratios. The result will be useful in forming quantitative estimates for the branching ratios of various exchange reactions in astrophysical applications. For exampl...
متن کاملHard underlying event correction to inclusive jet cross sections
Jets observed in hadron-hadron scattering contain a contribution from the “underlying event” that is produced by spectator interactions taking place incoherently with the major parton-parton collision, due to the extended composite structure of the colliding hadrons. Using a recent measurement of the double parton interaction rate, we calculate that the underlying event may be 2–3 times stronge...
متن کاملInfrared Safety in Factorized Hard Scattering Cross-Sections
The rules of soft-collinear effective theory can be used naı̈vely to write hard scattering cross-sections as convolutions of separate hard, jet, and soft functions. One condition required to guarantee the validity of such a factorization is the infrared safety of these functions in perturbation theory. Using e+e− angularity distributions as an example, we propose and illustrate an intuitive meth...
