Effective potential and vacuum stability
Vincenzo Branchina, Hugo Faivre, Vincent Pangon
By following previous work on this subject, we investigate the issue of the instability of the electroweak vacuum against the top loop corrections by performing an accurate analysi…
Effective potential (in)stability and lower bounds on the scalar (Higgs) mass
Vincenzo Branchina, Hugo Faivre
It is widely believed that the top loop corrections to the Higgs effective potential destabilise the electroweak (EW) vacuum and that, imposing stability, lower bounds on the Higgs…
On the direct CP violation parameter epsilon prime
M. S. Sozzi
We review different definitions of the parameter describing direct CP violation in neutral kaon decays, which was precisely measured in recent experiments, and point out the i…
Effective action and the quantum equation of motion
V. Branchina, H. Faivre, D. Zappalà
We carefully analyse the use of the effective action in dynamical problems, in particular the conditions under which the equation $\frac{δ\Ga} {δϕ}=0$ can be used as a quantum equa…
