Introducing The Particle Lab

We've spent the last while building something we think belongs on a science communication site more than a wall of text ever could: a place to play with the physics, not just read about it.

The Particle Lab is six small interactive tools, all in one page:

• A 3D collision visualizer — fire two proton beams down the pipe, watch them collide, and inspect the decay products.
• A Feynman diagram builder — place vertices, draw fermion/photon/gluon/boson lines by hand, and export your diagram as PNG or SVG.
• An invariant mass analyzer — generate LHC-style event samples and watch a resonance peak emerge from the background, just like the 2012 Higgs discovery plots.
• A particle properties explorer — search the Standard Model, then bend the "what-if" dials to see what changes if a particle's mass or lifetime were different.
• A decay chain simulator — pick a parent particle and step through real branching ratios, generation by generation.
• An event selector and lab notebook — apply kinematic cuts to a mock event stream, write up your observations, and generate a printable report.

Nothing here needs an account or a download — it's all client-side, autosaves to your browser, and runs on the same page you're reading this on. Go collide something.
