In recent years, searches for the light and heavy charged Higgs bosons havebeen done by the ATLAS and the CMS collaborations at the Large Hadron Collider(LHC) in proton-proton collision. Nevertheless, a definitive search is aprogram that still has to be carried out at the LHC. The experimentalobservation of charged Higgs bosons would indicate physics beyond the StandardModel. In the present work, we study the scaled-energy distribution ofbottom-flavored mesons ($B$) inclusively produced in polarized top quark decaysinto a light charged Higgs boson and a massless bottom quark at next-to-leadingorder in the two-Higgs-doublet model; $t(\uparrow)\to bH^+\to BH^++X$. Thisspin-dependent energy distribution is studied in a specific helicity coordinatesystem where the polarization vector of the top quark is measured with respectto the direction of the Higgs momentum. The study of these energy distributionscould be considered as a new channel to search for the charged Higgs bosons atthe LHC. For our numerical analysis and phenomenological predictions, werestrict ourselves to the unexcluded regions of the MSSM $m_{H^+}-\tan\beta$parameter space determined by the recent results of the CMS \cite{CMS:2014cdp}and ATLAS \cite{TheATLAScollaboration:2013wia} collaborations.
