Cohen's d and Bayes Factor
It seems they should be related since d is the size of the effect and is related to the difference between means, and Bayes Factor is the ratio of Alternative likelihood to Null likelihood, and Alternative likelihood should be related to the difference between means. Is there a formula? Or Correlation?

Yes. See http://www.ejwagenmakers.com/2016/LyEtAl2016JMP.pdf for details and equations.
We use this fact in our "Summary Stats" module, which takes t and N to produce a comprehensive Bayesian analysis.
