MONUMENT Biweekly meeting- Dec 4, 2024 minutes

Eli:
- 2D hist produced with LF data
- Only 1 C1/C2 coincidence window within 100 ns
- No distortion in LF data. So eta parameter not required
- Constrained muonic X-ray position (withi +/- 0.5 keV); separate sigma for muonic X-ray and the gamma ray to avoid the drift of gamma line
- Fit analysis: prompt line (gamma) represented via delta function and muX-ray via delta func X expo; combined fit

Q. Slava: Why do you think gamma line should have a drift
A. Christoph: O(~10%) correlation in intensities of muX and gammas

Toy study:
- Asymmetric timing, 2 gaussians with 2 means and different left/right tails
- Tail fit ad splined convolution- using full time profile
- Convolution fit more sensitive than tail fit

- Introduce major effects in the study; binning for ALPACA, dead-time for MIDAS

Dhanurdhar:
- Initial 136Ba lifetime analysis from ALPACA

Suggestions:
- Be careful with combining errors as they could be correlated
- beta parameter fixed in Eli's analysis
- look for distributions of free parameters in the fit
- Fit amplitude parameter can go < 0 to avoid any bias
