I need to break this rule because I have some intriguing pictures to show you.

Viewers discretion is advised.

From particles...

I have been involved in data analysis collected by the LHCb experiment since 2009.

Search for CP Violation ( CP / ) on hadronic charm 3-body decays:

Model independent: statistical comparison of the populations for particle and antiparticle in 2D intervals (bins) of DP (looking for local variations on the significance

  • f the difference in the populations).

Direct measurement of weak relative phase: multidimensional fit to DP (full Dalitz plot analysis).

B ✦ pseudoscalar ✰ vector: ACP measurement by CPT constraint (new model independent method).

From particles...

Amplitude analysis of the decay D✰ ✦ ✙✙✰✙✰ with LHCb data. Analysis made with full LHCb 2012 data, ✘600K events last analysis: CLEO-c ✘ 2K events.

[Phys.Rev.D76012(2007)]

Challenging model (It seemed impossible, so I liked it):

Very large samples ✦ detailed studies of light meson spectroscopy:

Low & high mass scalars, ✚✭770✮✦✭782✮ interference, etc. High levels of background ✦ Multivariate Analysis.

Fit with isobar model (sum of interfering resonances): very challenging.

Binned and unbinned maximum likelihood fit.

Complicated structure of the S-wave.

MI-PWA fit implemented for the first time on this channel.

Decay points are black boxes (we prefer to assume the FF) Machine Learning is a black box (sure, but I would rather be wrong with its guidance).
