B-tagging studies in $HH \rightarrow 4b$ analysis at $\sqrt{s} = 8$ TeV

We search for heavy resonances decaying into $HH \rightarrow 4b$, resulting in a dijet topology. Subjet b-tagging is explored as background discriminator, and feasibility studies in background estimations are done using an ABCD method. We find that 3 and 4 subjet b-tags result in the most efficient...

description We search for heavy resonances decaying into $HH \rightarrow 4b$, resulting in a dijet topology. Subjet b-tagging is explored as background discriminator, and feasibility studies in background estimations are done using an ABCD method. We find that 3 and 4 subjet b-tags result in the most efficient categories. Using these categories, we construct a background estimation to be used in further analysis in $HH \rightarrow 4b$ channel.
