3D Collision Visualizer
Two proton beams race down the pipe and collide. Glowing sprites are the decay products — drag to orbit, scroll to zoom.
Beam Controls
Saved Events
Feynman Diagram Builder
Place vertices, connect them with the right line style, and export your diagram.
Preloaded Currents
Builder Hints
Place two vertices, then choose a line type and drag from one to another. Charge and fermion number must flow through every vertex — conservation laws must balance at every coupling.
Invariant Mass Analyzer
Simulate LHC-style events, hunt for the resonance peak rising above the background, and compare to known particle masses.
Dataset
Particle Properties Explorer
The Standard Model, catalogued. Search below, open a card, and adjust the "what-if" dials to imagine altered particles.
Decay Chain Simulator
Choose a parent particle and watch it cascade downward, branch by branch, with real branching ratios.

Event Selector & Lab Notebook
Filter a mock event stream with kinematic cuts, then write up what you caught and generate a printable report.
