# Conditions of positivity and unitrity in the most general 2HDM via measurable quantities

Presented by Prof. Ilya GINZBURG

## Content

The well known conditions of positivity and unitrity in the 2HDM are written usually via parameters of potential $\lambda_a$ which values cannot be obtained from measurements unambigously. We express these very conditions in terms of measurable quantities. These conditions cannot be checked soon since they include values of some triple and quartic Higgs couplings (with charged Higgs bosons).
