1. b-ID Four taggers currently being worked on for p13
Secondary Vertex
Soft muons in jets
Two Impact parameter taggers:
CSIP
Jet Lifetime probability
Documentation and plots available on the b-id webpage: Follow the link
Official Certified b-Taggers (But beware the process of certification has started, but not yet certified)
Available Macros on TMBTrees for all four of them
Code for TMB exists in various stages of development.
some done, some done but not compiling, some still being written.

2. b-ID certification What is stalling us?
The tracking in p13 seems to be mysterious.
Better resolutions
But, too many fakes
We did not expect this, as we had tested the apparently “p13” equivalent GTR+HTF in the TARC samples.
At the moment we will go back and do a comparison on the same muon+jet and background runs p11 vs p13
Hopefully this is help us understand the issues causing limiations
In p13 efficiency lower by 20% or so and background up by a factor of 2 or more for pT cuts on track of 0.5 GeV. Can control this rate by raising pT cut (which is probably not very desirable for most physics.)
