The Lived Experiences of Chinese International Students Preparing for the University-To-Work Transition: A Phenomenological Qualitative Study

Chinese international students have been the largest growing number of international students on U.S. college and university campuses for the last ten years. However, there is minimal research literature that pertains to Chinese international students’ experiences on U.S. campuses and currently no research literature that reflects the entirety of their experience studying in the U.S. The purpose of thisphenomenological qualitative study was to give a voice to Chinese international students who are preparing for the university-to-work transition to better understand their experiences as international students in the United States, specifically the types of transitional stressors they experienced and how they coped with these stressors. Five major themes and the essence of the participants emerged from the data analysis and are presented, discussed, and implication for campus based mental health professionals are provided

Searching for Dark Photons with Maverick Top Partners

In this paper, we present a model in which an up-type vector-like quark (VLQ) is charged under a new $U(1)_d$ gauge force which kinetically mixes with the SM hypercharge. The gauge boson of the $U(1)_d$ is the dark photon, $\gamma_d$. Traditional searches for VLQs rely on decays into Standard Model electroweak bosons $W,Z$ or Higgs. However, since no evidence for VLQs has been found at the Large Hadron Collider (LHC), it is imperative to search for other novel signatures of VLQs beyond their traditional decays. As we will show, if the dark photon is much less massive than the Standard Model electroweak sector, $M_{\gamma_d}\ll M_Z$, for the large majority of the allowed parameter space the VLQ predominately decays into the dark photon and the dark Higgs that breaks the $U(1)_d$ . That is, this VLQ is a `maverick top partner' with nontraditional decays. One of the appeals of this scenario is that pair production of the VLQ at the LHC occurs through the strong force and the rate is determined by the gauge structure. Hence, the production of the dark photon at the LHC only depends on the strong force and is largely independent of the small kinetic mixing with hypercharge. This scenario provides a robust framework to search for a light dark sector via searches for heavy colored particles at the LHC.Comment: 40 pages and 11 figure
