PDG Particle Properties

Properties of every known particle from the Particle Data Group (PDG). Currently 6,506 particles.

Dataset description

The Particle Data Group (PDG) is THE definitive reference for particle physics properties, used by every particle physicist worldwide. This dataset provides a machine-readable version of the PDG particle listings, including masses, widths, lifetimes, quantum numbers, and decay properties for all known elementary particles, hadrons, and nuclei.

Data is sourced via the particle Python package which provides clean, programmatic access to the full PDG dataset.

Schema

Column	Type	Description
`pdg_id`	int64	PDG Monte Carlo particle ID
`name`	string	Particle name (e.g. "pi+", "K*(892)0")
`latex_name`	string	LaTeX-formatted name
`mass_mev`	float64	Mass (MeV/c^2)
`mass_uncertainty_mev`	float64	Mass upper uncertainty (MeV/c^2)
`width_mev`	float64	Decay width (MeV)
`width_uncertainty_mev`	float64	Width upper uncertainty (MeV)
`charge`	float64	Electric charge (units of e)
`spin`	float64	Spin J
`parity`	Int64	Parity P (+1 or -1)
`isospin`	string	Isospin I
`g_parity`	Int64	G-parity (+1 or -1)
`c_parity`	Int64	C-parity (+1 or -1)
`anti_flag`	int64	Anti-particle flag
`is_self_conjugate`	bool	Whether particle is its own antiparticle
`lifetime_ns`	float64	Lifetime (nanoseconds)
`ctau_mm`	float64	Proper decay length c*tau (mm)

Quick stats

6,506 particles in the database
6,431 with measured mass
522 with measured width
88 self-conjugate particles
Heaviest particle: Ds273 (254,437 MeV)

Usage

from datasets import load_dataset

ds = load_dataset("juliensimon/pdg-particle-properties", split="train")
df = ds.to_pandas()

# All mesons (PDG ID 100-999)
mesons = df[(df["pdg_id"].abs() >= 100) & (df["pdg_id"].abs() < 1000)]

# Mass spectrum plot
import matplotlib.pyplot as plt
masses = df[df["mass_mev"].notna()]["mass_mev"]
plt.hist(masses[masses < 5000], bins=100, log=True)
plt.xlabel("Mass (MeV/c^2)")
plt.ylabel("Count")
plt.title("Particle Mass Spectrum")

# Stable particles (no measured width)
stable = df[df["width_mev"].isna() & df["mass_mev"].notna()]

# Heaviest particles
heaviest = df.sort_values("mass_mev", ascending=False).head(20)
