  1. 2. Describing New Physics by EFTs

  2. 3. Factorization Beyond Coherence
    Dominik Schwienbacher (University of Bern)
    16/03/2026, 14:00

    I derive a novel factorization theorem for N-jettiness at hadron
    colliders, which incorporates coherence-violating effects induced by
    Glauber gluons and several new momentum modes. Their interplay generates
    coherence-violating logarithms (CVLs) starting at four-loop (N≥1) or
    five-loop order (N=0). I show the anomalous dimensions required for the
    resummation of CVLs and establish a general...

  6. 7. Hamiltonian Truncation and Effective Field Theory
    Kara Farnsworth
    18/03/2026, 10:00

    Hamiltonian truncation is a nonperturbative numerical method for calculating observables of a quantum field theory by truncating the Hilbert space to states with energy below a maximum energy cutoff. In this talk I will provide an overview of effective field theory techniques applied to Hamiltonian truncation calculations, focusing on improving convergence and handling marginal interactions in...

  10. 10. Trace anomalies and the dilation-graviton amplitude
    Denis Karateev (Universite de Geneve (CH))
    19/03/2026, 11:30

    We consider 3+1 dimensional Quantum Field Theories (QFTs) coupled to the dilaton and the graviton. We show that the graviton-dilaton scattering amplitude receives a universal contribution which is helicity flipping and is proportional to (∆c − ∆a) along any RG flow, where ∆c and ∆a are the differences of the UV and IR c- and a-trace anomalies respectively. This allows us to relate (∆c − ∆a) to...

  12. 13. Construction and limitations of EFTs for hot QFT
    Philipp Schicho (University of Geneva)
    20/03/2026, 09:00

    Finite-temperature effective field theories (EFTs) were originally developed to study thermodynamics and phase transitions in non-Abelian gauge theories. More recently, they have experienced renewed interest as a tool for determining soft contributions to real-time lightcone observables.

    In the context of cosmological phase transitions, the construction of such EFTs has reached new levels...

  13. 12. Shell EFT, Everywhere, All Orders at Once
    Dimitri Kosmopoulos
    20/03/2026, 10:30

    A key property that shapes the gravitational waveform of binary systems is the tidal deformability of their constituents, quantified by the Love numbers. In modern treatments of the gravitational two-body problem, the binary dynamics are described within an effective field theory (EFT), where Love numbers enter as Wilson coefficients encoding the finite-size response of each object. In this...
