[Peter Woolley]

Hi,

Can someone give me some background info on this forumla for the cross section of interaction between two spinless particles.

Any information will be of use.

Pete.

The Breit-Wigner formula is a mathematical equation used to describe the cross section of interaction between two spinless particles, such as in nuclear physics or particle physics. It was developed by the physicists Gregory Breit and Eugene Wigner in the 1930s and has since become an important tool in understanding particle interactions.

The formula takes into account the energy dependence of the interaction and is based on the concept of resonance. In particle physics, a resonance occurs when a particle is created with a certain energy and then decays into other particles. The Breit-Wigner formula helps to calculate the probability of this type of interaction occurring at a given energy.

The formula is also used to describe the shape of a resonance peak in particle scattering experiments. This peak represents the energy at which the particles are most likely to interact, and the width of the peak is related to the lifetime of the resonance.

In addition to its use in particle physics, the Breit-Wigner formula has also been applied in other fields such as nuclear physics, astrophysics, and even in the analysis of financial data. It is a versatile and powerful tool in understanding the behavior of particles and their interactions.

I hope this information helps to give you a better understanding of the Breit-Wigner formula and its significance in the study of particle interactions. If you have any further questions, please don't hesitate to ask. Good luck with your research!
