5d Coulomb Branches and 6d Anomaly Cancelation

In this talk, I will present Coulomb branches and Chern- Simons terms from the compactification of M-theory on elliptically fibered Calabi-Yau threefolds. I will further check that the uplifted theory in 6d is anomaly-free. I will focus on the theory with a gauge group SU(2)xG2, which plays a major role in the classification of superconformal theories.
