Positivity bounds in scalar-QED EFT at one-loop level
Yunxiao Ye, Xiao Cao, Yu-Hang Wu +1
Understanding the implication of positivity bounds on loop-generated dim-8 operator coefficients is a nontrivial task, as these bounds only strictly hold when all the contributions…

Positivity Bounds in Scalar Effective Field Theories at One-loop Level
Yunxiao Ye, Bin He, Jiayin Gu
Parameters in an effective field theory can be subject to certain positivity bounds if one requires a UV completion that obeys the fundamental principles of quantum field theory. T…
