TLDR
In this article, a search for a charged Higgs boson (H+) in t (t) over bar decays is presented, where one of the top quarks decays via t -> H(+)b, followed by H+ -> two jets (c (s) over bars).

Fingerprinting nonminimal Higgs sectors

Shinya Kanemura, +3 more
- 12 Jun 2014 - 
TL;DR: In this paper, the authors evaluate expected excluded regions for the mass of additional neutral Higgs bosons from direct searches at the LHC with the 14 TeV collision energy in the two Higgs doublet models with a softly broken discrete symmetry, and demonstrate how the pattern of deviations can be different among various Higgs sectors that predict the electroweak rho parameter to be unity.

The anti-$k_t$ jet clustering algorithm

Matteo Cacciari, +2 more
- 16 Apr 2008 - 
TL;DR: The anti-k-t algorithm as mentioned in this paper behaves like an idealised cone algorithm, in that jets with only soft fragmentation are conical, active and passive areas are equal, the area anomalous dimensions are zero, the non-global logarithms are those of a rigid boundary and the Milan factor is universal.
