Task proposal:

1. Time-dependent fluxes for SNOwGLoBES

2. Timing resolution studies for PDS

1. Time-dependent fluxes for SNOwGLoBES (previously)

- SNOwGLoBES have the Hüdepohl et al. SN model for time-dependent flux;

- Neutronization burst: valuable information for MO estimation

From my last presentation on SNB/LE meeting:

- Sum of events in neutronization * D2;

- Dist. from 1 to 100 kpc;

- Distance uncertainty

40 kton argon, σD = 1%

From my last presentation on SNB/LE meeting:

- Sum of events in neutronization * D2;

- Dist. from 1 to 100 kpc;

- Distance uncertainty

40 kton argon, σD = 20%

From my last presentation on SNB/LE meeting:

- Sum of events in neutronization * D2;

- Dist. from 1 to 100 kpc;

- Distance uncertainty

40 kton argon, σD = 50%

- Next step was to consider new models to determine the model uncertainty.

Burrows neutronization burst model data:

- Five progenitor models: 12, 15, 15 Shen EOS, 20, and 25 solar masses;

- Energy luminosity (1051 erg/s/MeV) for each time slice (- 40 ms to 80 ms, 0 = Lmax) in 40 energy bins for e, e and x.

Tasks:

- Create fluence files for SNOwGLoBES flux folder; ✅- Calculate MSW oscillations for ih and nh and generate the flux

files; ✅- Run SNOwGLoBES through the new flux files; ✅ - Obtain the events per bin histogram for no oscillation, nh and ih;✅- Continue my MO studies.

1. Time-dependent fluxes for SNOwGLoBES (results)

In the garching model, anti nue and nux start to rise after neutronization burst, while for Burrows model them start right at the neutronization peak

Garching Burrows

Main idea: use the notch in SN time-dependent flux

- Sub-ms resolution;

- Burrows model

2. Timing resolution studies for PDS

Unfortunately we can't see the notch in the burrows model after SNOwGLoBES =(
