Examples for

Particle Interactions

Wolfram|Alpha has experimental data on decay rates and scattering cross sections for many processes involving subatomic particles. See plots of scattering cross sections across a range of center-of-mass energies. See quantum numbers of particles involved in an interaction and potential decay products. Learn about reactions related to nuclear fission.

Scattering

Learn about collision and scattering processes commonly studied at accelerator centers.

Get particle collision data for specified beam types:

proton anti-proton collision

electron positron scattering

pion beam interactions

Specify particles symbolically:

K^+ + p reactions

p + gamma scattering

p-bar n -> anything

Get data at a particular center-of-mass energy:

pi+ interaction 5 GeV

p n scattering 4 GeV center of mass

Specify both incident and out-going particles:

K^- + p -> p + K^-

pi^- + p -> p + pi^- 3 GeV
