Algebraic Geometry in String Theory Seminar Speaker: Alessandro Chiodo, IMJ-Paris Rive Gauche (Jussieu) Title: The logarithmic double ramification locus Abstract: Given a family of smooth curves C -> S with a line bundle L on C, it is natural to study the locus of points x in S where L_x is trivial on C_x. When the family […]
Mathematical Aspects of Scattering Amplitudes Lecture Speaker: Tomasz Taylor, Northeastern University Title: Progress in Yang-Mills-Liouville Theory
Quantum Matter in Mathematics and Physics Seminar Speaker: Jesse Thaler, MIT Title: What Observables are Safe to Calculate? Abstract: In collider physics, perturbative quantum field theory is the workhorse framework for computing theoretical predictions to compare to experimental measurements. An observable is called "safe" if its cross section can be predicted order-by-order in perturbation theory […]

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 […]
