Formulate symbolic helicity amplitude model for p γ → η π⁰ p #17

Open shenvitor opened 2 weeks ago

Working on https://github.com/ComPWA/gluex-nstar/pull/13 for $p \gamma \to \eta \pi^0 p$ via ComPWA based on the example in https://tensorwaves.readthedocs.io/stable/amplitude-analysis/

Update: Before fix https://github.com/ComPWA/gluex-nstar/issues/24 ... First make this example to have visible outcomes of assuming to use the resonances and model via qrules and ampform to show how the amplitude models symbolically behave now by plotting the results such as phsp Dalitz plots and model weighted results, and mass distribution, etc.

For the record: while investigating N* in this channel, I find out something interesting about N(1440) Roper resonance – solution to the fifty year puzzle
