Sanford-Wang parameterisation: Difference between revisions

no edit summary
The Sanford-Wang parameterisation is a an empirical formula used to model the production of [[pions]] in nuclear interaction of the form p+A→A → <math>\pi^+</math>+X where a beam of high-energy [[protons]] hit a material.
Its formula for the double-differential [[Cross section (physics)|cross section]] with respect to momentum (p) and solid angle (<math>\Omega</math>) is as follows.
