11:00 - 12:00 Wednesday Weekly Seminar - Hybrid Format Exploring Axion-Like Particle Couplings through Single Top tW-Channel and Top Pair Production at the LHC School PARTICLES AND ACCELERATORS Abstract: In this paper, we explore the interactions between light axion-like particles (ALPs) and top quarks, gluons, and W-bosons. Utilizing high-energy probes at the LHC, we probe these couplings in the context of single top quark production associated with a W-boson and an ALP. We analyze the latest LHC Run II data on tt spin correlation measurements to establish constraints on these couplings. Additionally, we compare these constraints with those derived from loop-induced couplings and indirect searches involving B-meson decays. Furthermore, we derive two-dimensional limits on the ALP couplings with top quarks and gluons.< ... 15:30 - 17:00 Geometry and Topology Weekly Seminar Complex, Symplectic, and Kahler Geometry School MATHEMATICS Kahler manifolds appear naturally in both Algebraic and Differential Geometry: projective complex varieties from Algebraic Geometry, and smooth manifolds with Riemannian metrics with holonomy U(n). Understanding when a manifold may admit a Kahler structure and how far it is from that is a key problem in geometry. Classically, tools from global analysis (harmonic forms and Hodge theory) provide striking topological properties of Kahler manifolds, linking topology and analysis. We shall review this circle of ideas, and recent results on the construction of manifolds admitting complex structures (and even both complex and symplectic struc ... 18:00 - 19:00 Ph. D.
