What is pdg?

PDG generally refers to the Particle Data Group.

The Particle Data Group (PDG) is a collaborative project that compiles and disseminates information on particle physics. Its primary output is the Review of Particle Physics, a comprehensive compilation of data on the properties of elementary particles and related topics.

Key aspects of the PDG and its work include:

• Compiling Data: The PDG gathers data from experiments worldwide, critically evaluates it, and averages or fits the data to determine the best values for particle properties. This includes information about particles like the <a href="https://www.wikiwhat.page/kavramlar/Quarks">quarks</a>, <a href="https://www.wikiwhat.page/kavramlar/Leptons">leptons</a>, and bosons.

• Review of Particle Physics: This annual publication includes summary tables of particle properties, mini-reviews on specific topics in particle physics, and useful formulas and constants. It's considered the standard reference for the field. It covers topics ranging from the <a href="https://www.wikiwhat.page/kavramlar/Standard%20Model">Standard Model</a> of particle physics to searches for new phenomena.

• Online Resources: The PDG maintains a comprehensive website (pdg.lbl.gov) with up-to-date information and data tables. This includes searchable databases, interactive plots, and downloadable data.

• Community Resource: The PDG serves as a vital resource for particle physicists, astrophysicists, and other scientists who need reliable information about particle properties. Its work is essential for research and education in the field.
