Researchers test the Standard Model through high-energy collisions, precision measurements, rare processes, and neutrino experiments, while searching for new phenomena such as dark matter, new particles and forces, and new sources of matter-antimatter asymmetry.<\/p>\n<p>At Boston University, this work spans the energy and intensity frontiers, combining advanced detector development, electronics, computing, and data analysis.<\/p>\n<h2>What we study at BU<\/h2>\n<ul>\n<li><strong>CMS at the Large Hadron Collider<\/strong> \u2014 BU is an institutional member of the<br \/>\n<a href=\"https:\/\/cms.cern\/\" target=\"_blank\" rel=\"noopener\">CMS experiment at CERN<\/a>, with research spanning Higgs physics, dark matter and dark-sector searches, and searches for new particles and interactions. BU groups also play major roles in preparing CMS for the High-Luminosity LHC through detector and electronics development, triggering and data acquisition, and advanced computing.<\/li>\n<li><strong>Mu2e<\/strong> \u2014 The <a href=\"https:\/\/mu2e.fnal.gov\/\" target=\"_blank\" rel=\"noopener\">Mu2e experiment at Fermilab<\/a> searches for the conversion of a muon directly into an electron, a process so strongly suppressed in the Standard Model that its observation would be unambiguous evidence for new physics. BU researchers contribute to the experiment&#8217;s instrumentation, commissioning, simulation, and physics analysis.<\/li>\n<li><strong>Super-Kamiokande, T2K, and Hyper-Kamiokande<\/strong> \u2014 BU researchers study neutrino oscillations, CP violation, neutrino mass ordering, proton decay, and astrophysical neutrinos using <a href=\"https:\/\/www-sk.icrr.u-tokyo.ac.jp\/en\/sk\/\" target=\"_blank\" rel=\"noopener\">Super-Kamiokande<\/a> and the <a href=\"https:\/\/t2k-experiment.org\/\" target=\"_blank\" rel=\"noopener\">T2K experiment<\/a>. BU is also participating in <a href=\"https:\/\/www-sk.icrr.u-tokyo.ac.jp\/en\/hk\/\" target=\"_blank\" rel=\"noopener\">Hyper-Kamiokande<\/a>, the next-generation water Cherenkov experiment now under construction in Japan.<\/li>\n<li><strong>Neutrino properties and neutrinoless double-beta decay<\/strong> \u2014 BU researchers investigate fundamental properties of neutrinos, including whether neutrinos are their own antiparticles, through experiments such as <a href=\"https:\/\/www.awa.tohoku.ac.jp\/KamLAND-Zen\/\" target=\"_blank\" rel=\"noopener\">KamLAND-Zen<\/a>, <a href=\"https:\/\/snoplus.phy.queensu.ca\/\" target=\"_blank\" rel=\"noopener\">SNO+<\/a>, and <a href=\"https:\/\/cupid.lngs.infn.it\/\" target=\"_blank\" rel=\"noopener\">CUPID<\/a>. The group also develops next-generation neutrino detection techniques through reactor-neutrino experiments and detector R&amp;D including PROSPECT, WATCHMAN, THEIA, and NuDot.<\/li>\n<li><strong>Dark-sector searches and new experimental techniques<\/strong> \u2014 BU researchers develop new ways to search for light and weakly coupled particles, including the <a href=\"https:\/\/arxiv.org\/abs\/2203.08322\" target=\"_blank\" rel=\"noopener\">DarkQuest experiment at FNAL<\/a> and the <a href=\"https:\/\/u.osu.edu\/milliqan\/\" target=\"_blank\" rel=\"noopener\">milliQan experiment at CERN<\/a>.
