# Analysis of b quark pair production signal from neutral 2HDM Higgs bosons at future linear colliders

The European Physical Journal C, Jun 2018

In this paper, the b quark pair production events are analyzed as a source of neutral Higgs bosons of the two Higgs doublet model type I at linear colliders. The production mechanism is $$e^{+}e^{-} \rightarrow Z^{(*)} \rightarrow HA \rightarrow b{\bar{b}}b{\bar{b}}$$ assuming a fully hadronic final state. The analysis aim is to identify both CP-even and CP-odd Higgs bosons in different benchmark points accommodating moderate boson masses. Due to pair production of Higgs bosons, the analysis is most suitable for a linear collider operating at $$\sqrt{s} = 1$$ TeV. Results show that in selected benchmark points, signal peaks are observable in the b-jet pair invariant mass distributions at integrated luminosity of 500 $$\hbox {fb}^{-1}$$.
