Abstract:
Future Higgs factories can reach impressive precision on Higgs property measurements. In this talk, we explore its sensitivity to new physics models at the electron-positron colliders. In particular, we focus on Type-II Two Higgs Double Models and MSSM as illustrative examples. We perform a global fit to various Higgs search channels to obtain the 95% C.L. constraints on the model parameter space. We compare the sensitivity of various future Higgs factories, namely Circular Electron Positron Collider, Future Circular Collider-ee and International Linear Collider. We also show the complementarity between Higgs precision and Z-pole measurements, as well as direct searches for new particles at future pp colliders.
Brief CV:
Shufang Su, Professor, Department of Physics, University of Arizona. She received her Ph.D from Massachusetts Institute of Technology in 2000. She was the John A. McCone Postdoc Fellow at California Institute of Technology from 2000 to 2003, and joined the faculty of the University of Arizona in 2003. She was promoted to tenured Associate Professor in 2009 and full professor in 2015. Her primary research interests are in theoretical particle physics, focusing on important connections between theory and experiment as well as links between particle physics, astrophysics and cosmology. She served as Chair-elect (2011), Chair (2012) and Past Chair (2013) of the American Physics Society (APS) Four Corners Section. In 2014, she was selected as APS Fellow in Division of Particles and Fields, for her fundamental contributions to the phenomenology of Higgs bosons, dark matter, supersymmetry, and other physics beyond the Standard Model, which have stimulated and guided experimental search programs.
