The authors' main claim Utilizing jet substructure techniques, we find that for buried Higgses in the 100-120 GeV range, a 5-sigma discovery can be expected with roughly 10-25 inverse fb of data at E_CM = 14 TeV.

The Higgs boson may dominantly decay to 4 light jets through a light pseudo-scalar intermediary: h -> 2 eta -> 4j, making reconstruction at the LHC particularly challenging. We explore the phenomenology of such "Buried Higgs" scenarios in which the primary discovery channel of the Higgs is in cascade decays of superpartners. QCD backgrounds that would otherwise overwhelm the Higgs decay are suppressed by the requirement of high p_T jets and large missing transverse momentum that are the typical signatures of TeV scale supersymmetry. Utilizing jet substructure techniques, we find that for buried Higgses in the 100-120 GeV range, a 5-sigma discovery can be expected with roughly 10-25 inverse fb of data at E_CM = 14 TeV. For lighter Higgs bosons, the signal is contaminated by hadronically decaying W bosons, and discovery remains an unsolved challenge.

The paper

Original abstract

The Higgs boson may dominantly decay to 4 light jets through a light pseudo-scalar intermediary: h -> 2 eta -> 4j, making reconstruction at the LHC particularly challenging. We explore the phenomenology of such "Buried Higgs" scenarios in which the primary discovery channel of the Higgs is in cascade decays of superpartners. QCD backgrounds that would otherwise overwhelm the Higgs decay are suppressed by the requirement of high p_T jets and large missing transverse momentum that are the typical signatures of TeV scale supersymmetry. Utilizing jet substructure techniques, we find that for buried Higgses in the 100-120 GeV range, a 5-sigma discovery can be expected with roughly 10-25 inverse fb of data at E_CM = 14 TeV. For lighter Higgs bosons, the signal is contaminated by hadronically decaying W bosons, and discovery remains an unsolved challenge.

Displaced Supersymmetry

Bilinear R-parity violation can make the lightest superpartner decay at detector-scale distances, hiding supersymmetry from prompt searches and allowing squarks near 450 GeV.

The paper maps about twenty exotic Higgs decay topologies onto the models that produce them and derives new Run 1 limits on several by reinterpreting existing ATLAS and CMS analyses.

This can be the dominant Higgs decay mode, rendering most collider searches insensitive and allowing a Higgs as light as 82 GeV (similar to [ref] though with a different RPV scenario, see also [ref] ).

However, in supersymmetric production, the Higgs can easily get boosted which collimates all of the Higgs decay products into a “fat jet." An effective algorithm for identifying these jets and reconstructing Higgs candidates is provided by Butterworth, Davison, Rubin and Salam (BDRS) [ref] , where it was used for reconstructing SM Higgs.
