Colloquium Speaker: Lance Dixon (SLAC, Stanford University) Title: The DNA of Particle Scattering Abstract: At the Large Hadron Collider, the copious scattering of quarks and gluons in quantum chromodynamics (QCD) produces Higgs bosons and many backgrounds to searches for new physics. At short distances, scattering in QCD can be evaluated in perturbation theory and leads to highly […]

Symmetry Colloquia - Global Categorical Symmetries May 2, 2024 Location: Room G-10, CMSA, 20 Garden Street, Cambridge MA 02138 Speaker: Clay Còrdova, University of Chicago Title: Particle-Soliton Degeneracies from Spontaneously Broken Non-Invertible Symmetry Abstract: We study non-invertible topological symmetry operators in massive quantum field theories in (1+1) dimensions. In phases where this symmetry is spontaneously broken […]
Symmetry Colloquia - Global Categorical Symmetries May 2, 2024 Location: Room G-10, CMSA, 20 Garden Street, Cambridge MA 02138 Speaker: Thomas Dumitrescu, UCLA Title: Symmetries, Invertible Field Theories, and Gauge Theory Phases Abstract: I will start with a brief overview of gauge theory phases in 3+1 dimensions through the lens of higher symmetries — in particular the realization […]
Symmetry Colloquia - Global Categorical Symmetries May 2, 2024 Location: Room G-10, CMSA, 20 Garden Street, Cambridge MA 02138 Speaker: Theo Johnson-Freyd, Dalhousie University and Perimeter Institute Title: The Universal Target Category Abstract: Hilbert's Nullstellensatz says that the complex numbers C satisfy a universal property among all R-algebras: every not-too-large nonzero commutative R-algebra maps to C. Deligne proved a similar statement […]
