The Heavy Photon Search experiment took its first data in a 2015 engineering run using a 1.056 GeV, 50 nA electron beam provided by CEBAF at the Thomas Jefferson National Accelerator Facility, searching for an electro-produced dark photon. Using 1.7 days (1170 nb$^{-1}$) of data, a search for a resonance in the $e^+e^-$ invariant mass distribution between 19 and 81 MeV/c$^2$ showed no evidence...

53. Search For a Light Pseudoscalar Higgs Boson with Boosted Topologies at CMS

A search is performed for a light pseudoscalar Higgs boson (a) motivated by the theoretical framework of two higgs doublet plus singlet models (2HDM+S). This search uses 2016 LHC data collected at 13 TeV by the CMS experiment, and analyses the decay channel H->a a->mu mu tau tau, with H being either the 125 GeV state or heavier Higgs boson. Final state tau leptons feature a boosted and...
