  We investigate the production and decay of a vector-like top partner ($T$)
with charge ${2}/{3}$ within the Two Higgs Doublet Model Type II (2HDM-II)
extended by a vector-like quark (VLQ) doublet ($TB$). This study focuses on the
decay sequence where the $T$ quark produces a charged Higgs boson ($H^+$) and a
bottom quark, followed by the $H^+$ decay into a top and bottom quark, due to
the small branching ratio for $H^+ \to \tau\nu$ in the studied region. Previous
research
\href{https://doi.org/10.1103/PhysRevD.109.055016}{[Phys.Rev.D109,055016]} has
shown that the decay pathway $T \to H^+b$ followed by $H^+ \to tb$ is dominant
across a significant portion of the parameter space. We analyze the collider
process $pp \to T\bar{T} \to (bH^+)(\bar{b}H^-) \to
(b(tb))(\bar{b}(\bar{t}b))$, resulting in final states enriched with bottom
quarks. Our findings highlight this channel as a promising avenue for
discovering the new top partner and charged Higgs boson, offering substantial
detection potential across a broad parameter space.
