Partition Functions of N=(2,2) Gauge Theories on S2 and Vortices (2014)
Journal Article

We apply localization techniques to compute the partition function of a two-dimensional N=(2,2)N=(2,2) R-symmetric theory of vector and chiral multiplets on S2. The path integral reduces to a sum over topological sectors of a matrix integral over the... Read More about Partition Functions of N=(2,2) Gauge Theories on S2 and Vortices.

Journal Article

Resummation and S-duality in N = 4 SYM (2014)
Journal Article

We consider the problem of resumming the perturbative expansions for anomalous dimensions of low twist, non-BPS operators in four dimensional NN = 4 supersymmetric Yang-Mills theories. The requirement of S-duality invariance imposes considerable rest... Read More about Resummation and S-duality in N = 4 SYM.

The infrared fixed points of 3d N = 4 USp(2N) SQCD theories (2018)
Journal Article

We derive the algebraic description of the Coulomb branch of 3d N = 4 U S p ( 2 N ) SQCD theories with N f fundamental hypermultiplets and determine their low energy physics in any vacuum from the local geometry of the moduli space, identifying the i...

The (2, 0) superconformal bootstrap (2016)
Journal Article

We develop the conformal bootstrap program for six-dimensional conformal field theories with (2, 0) supersymmetry, focusing on the universal four-point function of stress tensor multiplets. We review the solution of the superconformal Ward identities... Read More about The (2, 0) superconformal bootstrap.

6d dual conformal symmetry and minimal volumes in AdS (2016)
Journal Article

The S-matrix of a theory often exhibits symmetries which are not manifest from the viewpoint of its Lagrangian. For instance, powerful constraints on scattering amplitudes are imposed by the dual conformal symmetry of planar 4d N=4N=4 super Yang-Mill...

Universality of the hydrodynamic limit in AdS/CFT and the membrane paradigm (2009)
Journal Article

Holographic entanglement entropy and gravitational anomalies (2014)
Journal Article

We study entanglement entropy in two-dimensional conformal field theories with a gravitational anomaly. In theories with gravity duals, this anomaly is holographically represented by a gravitational Chern-Simons term in the bulk action. We show that...

The Five-loop Beta Function for a General Gauge Group (2017)
Journal Article

We present results for the gluon field anomalous dimension in perturbative QCD and derive the corresponding Beta function at five-loop order. All given results are valid for a general gauge group.

Sphalerons in composite and non-standard Higgs models (2017)
Journal Article

After the discovery of the Higgs boson and the rather precise measurement of all electroweak boson’s masses the local structure of the electroweak symmetry breaking potential is already quite well established. However, despite being a key ingredient... Read More about Sphalerons in composite and non-standard Higgs models.

Hopf solitons on compact manifolds (2018)
Journal Article

Hopf solitons in the Skyrme-Faddeev system on R3 typically have a complicated structure, in particular when the Hopf number Q is large. By contrast, if we work on a compact 3-manifold M, and the energy functional consists only of the Skyrme term (the... Read More about Hopf solitons on compact manifolds.

Generalized global symmetries and holography (2018)
Journal Article

We study the holographic duals of four-dimensional field theories with 1-form global symmetries, both discrete and continuous. Such higher-form global symmetries are associated with antisymmetric tensor gauge fields in the bulk. Various different rea... Read More about Generalized global symmetries and holography.

Amplitudes and correlators to ten loops using simple, graphical bootstraps (2016)
Journal Article

We introduce two new graphical-level relations among possible contributions to the four-point correlation function and scattering amplitude in planar, maximally supersymmetric Yang-Mills theory. When combined with the rung rule, these prove powerful... Read More about Amplitudes and correlators to ten loops using simple, graphical bootstraps.

Double-charming Higgs boson identification using machine-learning assisted jet shapes (2018)
Journal Article

We study the possibility of identifying a boosted resonance that decays into a charm pair against different sources of background using QCD event shapes, which are promoted to jet shapes. Using a set of jet shapes as input to a boosted decision tree,... Read More about Double-charming Higgs boson identification using machine-learning assisted jet shapes.

Prospects for new physics in τ→lμμ at current and future colliders (2017)
Journal Article

The discovery of lepton flavour violating interactions will be striking evidence for physics beyond the Standard Model. Focusing on the three decays τ∓→μ±μ∓μ∓, τ∓→e±μ∓μ∓ and τ∓→e∓μ∓μ±, we evaluate the discovery potential of current and future high-en...

The effect of thermal velocities on structure formation in N-body simulations of warm dark matter (2017)
Journal Article

We investigate the impact of thermal velocities in N-body simulations of structure formation in warm dark matter models. Adopting the commonly used approach of adding thermal velocities, randomly selected from a Fermi-Dirac distribution, to the gravi...

Multi-Higgs-boson production in gluon fusion at 100 TeV (2016)
Journal Article

We carry out a detailed study of multi-Higgs production processes in the gluon fusion channel in the high-energy regime relevant to future circular hadron colliders and in the high-Higgs-multiplicity limit (≥20). Our results are based on the computat... Read More about Multi-Higgs-boson production in gluon fusion at 100 TeV.

Associated production of a top pair and a W boson at next-to-next-to-leading logarithmic accuracy (2016)
Journal Article

We consider soft gluon emission corrections to the production of a top-antitop pair in association with a W boson at the Large Hadron Collider. We obtain a soft-gluon resummation formula for this production process which is valid up to next-to-next-t...
