New single Lambda and wrong tag lines for sexaquarks

Patrick Koppenburg requested to merge pkoppenb-Xib2SpbarKp into master

Sexaquarks in \Xi_b^0\to S\bar{p}K^+

Stripping for 2016-18 data using SexaquarkbBaryonToKAndp Line

Fix of !1658 (merged).

Summer student Sam found no \Xi_b^0\to \bar{p}K^+\Lambda\Lambda signal in untagged \Xi_b^0 and @adoheny none in tagged \Xi_b^0. But maybe with only one \Lambda reconstructed there is a chance.

Also, @adoheny found that the background shape in \Xi_b^0\to \bar{p}K^+S is hard to model. Hence we need wrong-sign tags to get a clean background sample (though I bet there will be new backgrounds popping up).

Note to self: once this is approved I'll need a new run on simulation, superseding !1032 (merged). Note to @fhblanc @mvieites : If we see \Xi_b^0\to \Lambda\Lambda\bar{p}K^+ it should go to B2noC.

Output

Produces 9 nTuples

  • \Xi_b^0\to S\bar{p}K^+ straight from the stripping with non-reconstructed S
  • \Xi_b^{'-}\to \Xi_b^0 \pi^- with \Xi_b^0\to S\bar{p}K^+ and tagging pion
  • \Xi_b^{'-}\to \Xi_b^0 \pi^+ with \Xi_b^0\to S\bar{p}K^+ and tagging pion WS tagging pion
  • \Xi_b^0\to \Lambda\Lambda\bar{p}K^+ adding two hyperons
  • \Xi_b^{'-}\to \Xi_b^0 \pi^- with \Xi_b^0\to \Lambda\Lambda\bar{p}K^+ and tagging pion
  • \Xi_b^{'-}\to \Xi_b^0 \pi^+ with \Xi_b^0\to \Lambda\Lambda\bar{p}K^+ and WS tagging pion
  • \Xi_b^0\to \Lambda\bar{p}K^+ adding one hyperon and missing the other
  • \Xi_b^{'-}\to \Xi_b^0 \pi^- with \Xi_b^0\to \Lambda\bar{p}K^+ and tagging pion
  • \Xi_b^{'-}\to \Xi_b^0 \pi^+ with \Xi_b^0\to \Lambda\bar{p}K^+ and WS tagging pion

Note that the stripping calls the head \Lambda_b^0 and thus some particle names are changed.

Improvements on !1114 (merged) : add a single Lambda line and adds a wrong tag for each line. Thus from 4 we now have 9 tuples.

(supersedes !1114 (merged))

Instructions

When creating your merge request:

  • Add a label for your WG
  • Mark as "Draft:" until you're happy with the CI results
  • If the merge request supersedes a previous one, add a comment at the end of the header: (supersedes !<MR number>). Please state explicitly in the description if the superseded ntuples can be deleted immediately, or after the new merge request is finalised

When ready:

  • Remove the "Draft:" from the title:
  • Assign the merge request to you working group's DPA/RTA liaison

To find your working group's DPA/RTA liaison, see this page:
