  2. National discourse about STEM careers has dominated conversations about the need to meet the demands of the labor market. The ever increasing population diversity requires the participation of underrepresented groups, including women and individuals from racially minoritized backgrounds. However, for those at the intersections of historical and persistent marginality, such as Black female students, access to STEM majors, programs, and careers are particularly limited. This article uses observations, four student focus groups, document analysis, and survey data from a Black science conference to understand the experiences of Black women student attendees. Through an intersectional lens, we find that professional conferencesmore »can better serve Black female student participants by considering their nuanced experiences, barriers, and contributions to the field.« less

  5. A bstract A search is presented for a heavy W′ boson resonance decaying to a B or T vector-like quark and a t or a b quark, respectively. The analysis is performed using proton-proton collisions collected with the CMS detector at the LHC. The data correspond to an integrated luminosity of 138 fb − 1 at a center-of-mass energy of 13 TeV. Both decay channels result in a signature with a t quark, a Higgs or Z boson, and a b quark, each produced with a significant Lorentz boost. The all-hadronic decays of the Higgs or Z boson and ofmore »the t quark are selected using jet substructure techniques to reduce standard model backgrounds, resulting in a distinct three-jet W′ boson decay signature. No significant deviation in data with respect to the standard model background prediction is observed. Upper limits are set at 95% confidence level on the product of the W′ boson cross section and the final state branching fraction. A W′ boson with a mass below 3.1 TeV is excluded, given the benchmark model assumption of democratic branching fractions. In addition, limits are set based on generalizations of these assumptions. These are the most sensitive limits to date for this final state.« less
