WebJan 11, 2006 · Imagine cutting a (spherical!) grapefruit into two equal parts. The area of each of the flat circles you just created is called the cross sectional area. That differs from the (surface) area of the original grapefruit only in that you are calculating the area of different things (i.e. area is area!). Jan 11, 2006. Webcross sectional area). Similarly in nuclear physics: • Probability of a projectile to “hit” a target nucleus (i.e. interact with it, such as scatter from it or break it up) may be described by an analogous “cross section” (but not the actual, physical cross sectional area of the nucleus). • Different processes (reaction channels ...

What do we mean by "cross section" in particle physics?

WebThe term “cross section” is a berry of particle physics — its technical meaning is very different from the common usage. In everyday speech, “cross section” refers to a slice of an object.
