Factorization Beyond Coherence
Thomas Becher, Patrick Hager, Matthias Neubert +1
We derive a novel factorization theorem for -jettiness at hadron colliders, which incorporates coherence-violating effects induced by Glauber gluons and several new momentum mod…

Saving or Destroying the Universe with Axion-Like Particles
Anne Mareike Galda, Matthias Neubert
Light pseudoscalar resonances that couple to the Standard Model via non-renormalizable operators, such as axions and axion-like particles (ALPs), generate contributions to the reno…

Two-loop contributions of axion-like particles to electromagnetic and chromomagnetic form factors
Matthias Neubert, Marvin Schnubel
Axions and axion-like particles emerge in many models for physics beyond the Standard Model. Thus, they have gained increasing research interest in both experimental and theoretica…
