*“Precision High Scale Baryogenesis"*
**

_*Abstract*_

Baryogenesis should occur before Big Bang Nucleosynthesis to explain the 
observed cosmic matter-antimatter asymmetry. In order to describe 
baryogenesis precisely, one needs to describe the evolution of baryon 
and lepton flavor charges taking into account all the relevant Standard 
Model processes: Yukawa, electroweak sphaleron and QCD sphaleron 
interactions. In this talk I will first describe a full-flavor-covariant 
formalism and then introduce a new quark-flavor-covariant formalism. 
Then I will discuss application to SO(10) leptogenesis as well as 
cloistered baryogenesis. This work also results in the first generic 
baryogenesis public code BOLEH (BaryOn and Lepton charge Evolution in 
the Hot big bang).

*“Higher Point Positivity and Large-Nc QCD**"*
*
*

_*Abstract*_

Scattering amplitudes provide a powerful way to constrain effective 
field theories from the bottom-up, using only general physical 
consistency conditions such as unitarity and causality. Most existing 
bounds are based on four-point amplitudes. In this talk, I will explain 
how higher point amplitudes can be used to obtain new constraints that 
go beyond the four-point analysis. As a concrete example, I will apply 
the method to Large-Nc QCD.
