Di-Higgs 2020: Opportunities and Challenges

→ Asia/Shanghai
3rd-300# Meeting Room (Tsung-Dao Lee Institute (East wing of Pao Yue-Kong Library))

3rd-300# Meeting Room

Tsung-Dao Lee Institute (East wing of Pao Yue-Kong Library)
Description

The study of di-Higgs production at the LHC and prospective future high-energy colliders provides a unique window on the dynamics of electroweak symmetry-breaking. Within the Standard Model, non-resonant di-Higgs production provides access to the Higgs tri-linear self-coupling, providing a key test of the Higgs mechanism. Beyond the Standard Model, both resonant and non-resonant di-Higgs production are sensitive to extended Higgs sectors and their implications for a possible first order electroweak phase transition in the early universe. Experimentally, di-Higgs production offers a rich array of channels to be studied, with their associated challenges. 

This workshop will bring together theorists and experimentalists to discuss the theoretical implications and interpretation of di-Higgs production, the status of planned di-Higgs searches at the LHC, and the opportunities for new experimental searches at the LHC and beyond.
