Typos stops your evaluation of trilinears at[t] and ab[t] - you wrote (1/16Pi^2) as loop factor for these terms by mistake, and blow up at[0] and ab[0] seriously. There are also 2 other typos, one appears in the beta function of ab[t] \hbbis[t] should be hbbis[t]; the other one is systema should be system for the interpolation of mhu2 and mhd2. I feel, ...

The baryon non-conservation in the quantum theory is caused by the chiral anomaly, which leads to the baryon current $j_B^\mu = \sum_i \bar q_i \gamma^\mu q_i$ being not conserved as $$ \partial_\mu j_B^\mu \propto F\wedge F$$ where $F$ is the field strength tensor of the electroweak field. Now, $\int \partial_\mu j_B^\mu \propto \int F\wedge F$ is a ...
