Report meeting 15/10/2025 :

- Create new plot for calorimeter

- Investigate difference between SMASH and white leptons : from angular distribution or close pair effects only

- Change in RMQ cut : efficiency based cut, looser cut

- Impact of effective mass cut and purity analysis from SMASH

- NCALS cut impact on signal / background

- Start Systematics Uncertainties analysis

Report Meeting 13/11/2025 :

Invariant mass hist of PLUTO rho to see if low mass rho exists in this file or not

Put oAring Cut on all selection to compare simulations ( SMASH,white,PLUTO) and experimental data

SMASH NCALS theta for comparison

Use macro mac() to show multiple distribution between simulations and exp cut

Make cocktail by PLUTO for observables and efficiency matrix

Plot phi peak with and without smearing raw

Increase number of bin for phi

On the in efficiency part : check using relative kine object, ideal mom and ideal smeared mom to compare smearing quality

See how changed is the phi peak after smearing

Show efficiency self check in [0;2] to see with more details differences

Correction factor as function as opening angle ---> Plot also 2D hist for invariant mass and opening angle

Check if some regions lose efficiency or not
