Four presentations by faculty members of the Department of Physics, University of Arizona.
1. Imaging electron in action
Mohammed Hassan
Abstract: We are focusing on how to utilize the attosecond laser and electron microscopy technologies to image the electron motion in real time and space. This electron imaging would reveal new physics or allow us to see the physics we know from new perspective.
2. Boosted Higgs Boson Pair Production at the ATLAS Experiment
Rachel J. Hyneman
Abstract: Measurements of Higgs Boson Pair Production probe how the Higgs Boson interacts with itself. These self interactions serve as a test of our fundamental understanding of the Higgs Boson, and they may illuminate big physics questions, such as whether our universe is stable. I will present a recent measurement of Higgs Boson pair production from the ATLAS Experiment at CERN targeting the final state in which each Higgs Boson decays to a pair of collimated b-quarks, known as the boosted topology.
3. Predicting beauty-charm tetraquarks using lattice QCD
Stefan Meinel
Abstract: In 2021, LHCb discovered an exotic tetraquark meson containing two charm quarks and two light antiquarks, which decays through the strong interaction into three ordinary mesons. Similar tetraquarks containing bottom instead of charm quarks may be stable under the strong interaction. I will present recent lattice-QCD predictions for such systems.
4. Quantum dynamics on ultrafast timescales
Arvinder Sandhu
Abstract: Electronic couplings and correlations drive the time evolution of many common processes. I will show how we can quantify and control the underlying dynamics by employing coherent light-matter interactions on the femtosecond and attosecond timescales.
