WIP: Adding Xic2LambdaKPi and Xic2SigmaKPi modules

Xic2LambdaKPi module

Stripping lines for

$\Xi_c^+\to\Lambda^0K_S^0\pi^+$

and

$\Xi_c^0\to\Lambda^0K^-\pi^+$

with wide mass windows to partially reconstruct the decay modes with a

$\Sigma^0\to\Lambda\gamma$

where the photon is not reconstructed. The lines have been re-written with respect to the 2015/2016 stripping.

Xic2SigmaKPi module

Stripping lines for

$\Xi_c^+\to\Sigma^0K_S^0\pi^+$

,

$\Xi_c^0\to\Sigma^0K^-\pi^+$

and

$\Xi_c^+\to\Sigma^+K^-\pi^+$

with

$\Sigma^0\to\Lambda\gamma$

and

$\Sigma^+\to p \pi^0$

using long proton tracks only. Modes with a

$\Sigma^0$

are put in to cross-check partial reconstruction techniques planned for the lines above

Timings of the lines involving

\Sigma

, especially of the

\Xi_c^+\to\Sigma^+K^-\pi^+

line, are relatively high because sensitive cuts can only be made at a very late stage of the reconstruction. @cvazquez please double-check if this is OK.

@mstahl Did you contact Jinlin Fu, who also has a Xic2LambdaKpi line?

Hi @lohenry, No, I only saw @jfu 's line now. Maybe we can merge both lines in a clever way. I'm traveling this weekend and don't have too much time, but I'll try to have a look this evening. The main difference is probably that I would also like to capture the partially reconstructed

\Xi_c^+\to\Sigma^0 K^- \pi^+

decay and have a larger mass window

@mstahl you're overwriting the repository. Maybe you used git clone instead of lb-dev? I'm closing the MR, please open a new one (better to clean-up the branch).
