Description

We revisit the rare decay of the Higgs boson into two different quarks at the one-loop level in the Standard Model. We implement the GIM mechanism in a strict manner, by performing meticulous Taylor expansions of the amplitude's form factors, in order to get rid of spurious terms. We predict Br$(H\to uc)$=$1.63\times {10}^{-18}$, Br$(H\to ds)$=$9.07\times {10}^{-15}$, Br$(H\to db)$=$1.03\times {10}^{-8}$, Br$(H\to sb)$=$2.44\times {10}^{-7}$; our Br$(H\to uc,ds)$ are more suppressed than those previously reported in the literature.
