A particle physics model is essentially described by its Lagrangian. To simulate the production of events through event generators, 3 steps have to be taken. The Automatic Calculation project is to create the tools to make those steps as automatic (or programmed) as possible: I Feynman rules, coupling and mass generation
Interactions in the Standard Model. All Feynman diagrams in the model are built from combinations of these vertices. q is any quark, g is a gluon, X is any charged particle, γ is a photon, f is any fermion, m is any particle with mass (with the possible exception of the neutrinos), m B is any boson with mass. In diagrams with multiple particle ...

Template:Subatomic particle uses this template to display particles, e.g.: {{Subatomic particle|link=yes|Electron}} → e − is the same as {{Physics particle|e|TR=−|link=Electron}} → e − (an electron) {{Subatomic particle|Strange antib0}} → B 0 s is the same as {{Physics particle|anti=yes|B|TR=0|BR=s|BRc=1}} → B 0 s (a meson)
Particle-size analysis also helps the effectiveness of SAG Mills when crushing material. In the building industry, the particle size can directly affect the strength of the final material, as it observed for cement. [18] Two of the most used techniques used for the particle size characterization of minerals are sieving and laser diffraction.
The Weibull distribution or Rosin–Rammler distribution is a useful distribution for representing particle size distributions generated by grinding, milling and crushing operations. The log-hyperbolic distribution was proposed by Bagnold and Barndorff-Nielsen [9] to model the particle-size distribution of naturally occurring sediments. This ...

However, as the detector simulation is usually a complex and computationally expensive task, simple event analysis techniques are also performed directly on event generator results. Some automatic software packages exist, that help in constructing event generators and are sometimes viewed as generators of event generators or meta-generators .
