Bethe phase including proton excitations (2020)
Journal Article

We evaluate the contribution of inelastic intermediate states (such as p → N excitations) to the phase between the one-photon-exchange and the “nuclear” high energy pp scattering amplitudes as t → 0, caused by multiphoton diagrams. It turns out to be... Read More about Bethe phase including proton excitations.

Higgs self-coupling measurements using deep learning in the bb¯¯bb¯¯ final state (2020)
Journal Article

Measuring the Higgs trilinear self-coupling λhhh is experimentally demanding but fundamental for understanding the shape of the Higgs potential. We present a comprehensive analysis strategy for the HL-LHC using di-Higgs events in the four b-quark cha...

Towards constraining dark matter at the LHC: higher order QCD predictions for tt¯+ Z(Z → ν`ν¯`) (2019)
Journal Article

Triggered by ongoing dark matter searches in the top quark sector at the Large Hadron Collider we report on the calculation of the next-to-leading order QCD corrections to the Standard Model process pp → t t¯ + Z (Z → νℓ v¯¯¯ ℓ). This calculation is... Read More about Towards constraining dark matter at the LHC: higher order QCD predictions for tt¯+ Z(Z → ν`ν¯`).

The emergence of electroweak Skyrmions through Higgs bosons (2021)
Journal Article

Skyrmions are extended field configurations, initially proposed to describe baryons as topological solitons in an effective field theory of mesons. We investigate and confirm the existence of skyrmions within the electroweak sector of the Standard Mo... Read More about The emergence of electroweak Skyrmions through Higgs bosons.

Emergent gravity from hidden sectors and TT deformations (2021)
Journal Article

We investigate emergent gravity extending the paradigm of the AdS/CFT correspondence. The emergent graviton is associated to the (dynamical) expectation value of the energy-momentum tensor. We derive the general effective description of such dynamics... Read More about Emergent gravity from hidden sectors and TT deformations.

Higgs Boson studies at future particle colliders (2020)
Journal Article

This document aims to provide an assessment of the potential of future colliding beam facilities to perform Higgs boson studies. The analysis builds on the submissions made by the proponents of future colliders to the European Strategy Update process... Read More about Higgs Boson studies at future particle colliders.

Nonlocal gravity with worldline inversion symmetry (2020)
Journal Article

We construct a quadratic curvature theory of gravity whose graviton propagator around the Minkowski background respects wordline inversion symmetry, the particle approximation to modular invariance in string theory. This symmetry automatically yields... Read More about Nonlocal gravity with worldline inversion symmetry.

Scattering of compact oscillons (2020)
Journal Article

We study various aspects of the scattering of generalized compact oscillons in the signum-Gordon model in (1+1) dimensions. Using covariance of the model we construct traveling oscillons and study their interactions and the dependence of these intera... Read More about Scattering of compact oscillons.

Singular BPS boundary conditions in $$ \mathcal{N} $$ = (2, 2) supersymmetric gauge theories (2021)
Journal Article

We derive general BPS boundary conditions in two-dimensional N = (2, 2) supersymmetric gauge theories. We analyze the solutions of these boundary conditions, and in particular those that allow the bulk fields to have poles at the boundary. We also pr...
