This paper investigates the effects of parameters in the Bestest Little Higgs
Model (BLHM) on rare flavor-changing decays of the top quark. As a result,
flavor-changing phenomena are introduced in the BLHM for the first time. In
this study, we incorporate new flavor mixing terms between the light quarks of
the Standard Model (SM) and the fermions and bosons of the BLHM. We compute the
one-loop contributions from the heavy quark (B) and the heavy bosons
(W′±,ϕ±,η±,H±). Our findings demonstrate
that the branching ratios of decays t→qV and t→qh0, where q=u,c
and V=Z,γ,g, exhibit improvements compared to their counterparts in
the SM, except for the gluon case. Moreover, we observe that the processes with
higher sensitivity are Br(t→cZ)∼10−5, Br(t→cγ)∼10−6 and Br(t→ch0)∼10−8 within the appropriate parameter
space.Comment: 13 pages and 10 figure
