Samir Gambhir and Stephen Menendian, UCB – The Inclusiveness Index
The Physics IDEA Committee has invited Samir Gambhir, Director of the Equity Metrics Program, and Stephen Menendian, Assistant Director, members of the Othering & Belonging Institute, University of California, Berkeley, will present their findings on the Inclusiveness Index. They have ranked every US state (and 133 countries) by their levels of inclusion. The Inclusiveness Index examines inclusivity in terms of race, religion, gender (sex), sexual orientation, and disability, among other social groups using several measures. These include outgroup violence; political …

David Dunsky (LBNL) “Dark Radiation Constraints on Heavy QCD Axion Theories”
Abstract: The explicit breaking of the PQ symmetry by higher dimensional operators can spoil the dynamical relaxation of the strong CP angle to its minimum of zero. One solution to this PQ “quality problem” is to introduce heavy QCD axions. Such axions acquire a mass from physics occurring far above the QCD scale and possess a potential more robust to corrections from higher dimensional PQ breaking operators. However, in much of the (m_a, f_a) plane, heavy QCD axions can generate …
