The Breit-Wigner cross section for resonant particle decay takes the form: σ f i = π ℏ 2 q 2 2 j + 1 ( 2 S 1 + 1) ( 2 S 2 + 1) Γ i Γ f ( E − M c 2) 2 + Γ 2 / 4. I am looking to (non-relativistically) explain the origin of each of these terms. This question is concerned however with just the: Webgeneral form than the Breit-Wigner formula.

The relativistic Breit–Wigner distribution (after the 1936 nuclear resonance formula of Gregory Breit and Eugene Wigner) is a continuous probability distribution with the following probability density function, $${\displaystyle f(E)={\frac {k}{\left(E^{2}-M^{2}\right)^{2}+M^{2}\Gamma ^{2}}}~,}$$where … See more The probability of producing the resonance at a given energy E is proportional to f (E), so that a plot of the production rate of the unstable particle as a function of energy traces out the shape of the relativistic Breit–Wigner … See more In experiment, the incident beam that produces resonance always has some spread of energy around a central value. Usually, that is a See more Webe i k 0 t {\displaystyle e^ {ik_ {0}t}\,} 在 数理统计 中， 退化分布 （或 确定性分布 ）是指只有一种值的分布，是一种绝对事件的分布。. 比如，一个六面数值均相等的骰子；一枚正反双面一模一样的硬币。. 尽管它并不会随机出现数字，这种分布满足随机变量的定义 ... maplestory where is lania
