PDG Particle Properties
Credit: NASA/JPL-Caltech/STScI/CXC/SAO
Part of a dataset collection on Hugging Face.
Dataset description
Properties of every known particle from the Particle Data Group (PDG) -- THE definitive reference for particle physics, used by every particle physicist worldwide.
The PDG, based at Lawrence Berkeley National Laboratory, has published its Review of Particle Physics since 1957 -- the single most cited publication in high-energy physics. The PDG compiles and critically evaluates measurements from thousands of experiments at facilities like CERN's Large Hadron Collider, Fermilab, KEK, and SLAC to produce world-average values for particle masses, widths, lifetimes, and quantum numbers.
The dataset covers the full spectrum of known particles: the six quarks, six leptons, and gauge bosons of the Standard Model; the Higgs boson discovered at CERN in 2012; hundreds of mesons (quark-antiquark bound states) and baryons (three-quark bound states) organized by flavor quantum numbers; and light nuclei.
This machine-readable version supports automated analysis pipelines in high-energy physics, Monte Carlo event generators, detector simulation frameworks, and educational tools. It is also valuable for machine learning applications in particle identification and anomaly detection in collider data.
This dataset is suitable for tabular classification, tabular regression tasks.

charge |
float64 | Electric charge in units of the elementary charge e; quarks carry fractional charges (u/c/t: +2/3, d/s/b: -1/3); leptons and hadrons carry integer charges | -0.3333333333333333 | 0.0% |
spin |

g_parity |
Int64 | G-parity quantum number; +1 or -1; defined only for non-strange mesons with zero baryon number; null otherwise | 5 | 0.0% |
c_parity |
Int64 | Charge-conjugation parity C; +1 or -1; defined only for electrically neutral self-conjugate particles (e.g. pi0, photon, J/psi); null for charged particles | 5 | 0.0% |
anti_flag |
int64 | Relationship to antiparticle: 0 = own antiparticle (self-conjugate), 1 = particle (antiparticle listed separately), -1 = antiparticle entry | 1 | 0.0% |
is_self_conjugate |
bool | True if the particle is its own antiparticle (e.g. photon, pi0, Z boson, Higgs); false for particles with a distinct antiparticle | False | 0.0% |
