Glossary
- BR
- Beam Remnants; not much used since it may be confused with
Branching Ratio
- BSM
- Beyond-the-Standard-Model physics, as a generic term for anything
not contained within the SM
- FSR
- Final-State Radiation, implemented in terms of timelike showers
- ISR
- Initial-State Radiation, implemented in terms of spacelike showers
- MI
- Multiple Interactions, i.e. several (more or less) independent
parton-parton subcollisions as part of a hadron-hadron event (sometimes
also called MPI, with P for parton or parton-parton)
- MSSM
- Minimal Supersymmetric extension of the Standard Model
- PDF
- Parton Distribution Function (alternatively Parton Density
Function)
- PDG code
- a scheme for assigning unique integers, particle identity codes,
to known and hypothetical particles; code rules and tables are published
in the RPP (see below).
- pileup
- several hadron-hadron collisions in a bunch crossing
- RPP
- Review of Particle Physics, the biannual review by the ParticleData Group
(PDG) from which many Standard-Model parameter values and much particle data
has been taken (but, given the poor data on many hadron resonances, a lot of
extra (guess)work is needed)
- setting
- collectively used to denote all the boolean
flag
,
integer mode
, double-precision parm
and string word
variables that can be set by the user
to steer the behaviour of a run; normally particle data are considered
separately but clearly are closely related
- SM
- the Standard Model of particle physics
- SUSY
- SUperSYmmetry
