Argus background shape

For RooFit object, see RooArgusBG.

BEPC

Beijing Electron-Positron Collider. Currently the second ‘version’: BEPCII.

BESIII

Beijing Electron Spectrometer III

BOSS

BESIII Offline Software System

Breit-Wigner parametrization

• Analytical continuation of the Breit-Wigner parametrization

• Does not allow for extraction of pole parameters, only ratios

• Only works in case of narrow structure and if there are no other resonances nearby

• Can be used to extract pole parameters such as particle width

• Possible: energy dependent parameters

Chebychev polynomial

For RooFit object, see RooChebychev.

Dalitz plot

Used in case of three-body decays.
See PDG on Kinematics, section 47.4.3.1.

Data driven background estimate

Efficiency

Exclusive Monte Carlo simulation

You only generate events with decays that are of interest to your analysis.

Flatté parametrization

• Analytical continuation of the Breit-Wigner parametrization

• Does not allow for extraction of pole parameters, only ratios

IHEP

Institute of High Energy Physics, part of the CAS

Inclusive Monte Carlo simulation

You generate event as completely as possible. Since this takes a lot of computing resources, one usually makes use of the data sets that were reconstructed by the BOSS team for your version of BOSS. For the file locations of inclusive \(J/\psi\) samples, see this page [requires login].

Partial wave analysis

Polynomial background

For RooFit object, see RooPolynomial.

Rapidity

RooFit

See tutorial scripts.

Semantic versioning

See here. This is essentially a numbering scheme used for tagging versions of a package. Within BOSS, a package can for instance be given tag Package-01-04-03, where 01 is the major ID, 04 the minor ID, and 03 the patch ID.
