The ATLAS and CMS experiments have an ambitious search program for charged Higgs bosons. The two main searches for H^± at the LHC have traditionally been performed in the τν and t b decay channels, as they provide the opportunity to probe complementary regions of the Minimal SuperSymmetric Model (MSSM) parameter space. Charged Higgs bosons may decay also to light quarks, H^± → cs/cb, which represent an additional probe for the mass range below mt. In this work, we focus on H^± → μν as an alternative channel in the context of two Higgs doublet model type III. We explored the prospect of looking pp→ tb H^±, followed by H^±→μν signal at the LHC. Such a scenario appears in 2HDM type-III where couplings of the charged Higgs are enhanced to μν. Almost all the experimental searches rely on the production and decay of the charged Higgs are taken into account. We show that for a such scenario, the above signal is dominant for most of the parameter space, and H^± → μν can be an excellent complementary search. Benchmarks points are proposed for further Monte Carlo analysis.
