Precise QCD description of the Higgs boson transverse momentum spectrum (2018)
Journal Article

The transverse momentum () distribution of Higgs bosons at hadron colliders enables a detailed probe of its production dynamics and is a key ingredient to precision studies of Higgs boson properties, but receives very large QCD corrections. We obtain... Read More about Precise QCD description of the Higgs boson transverse momentum spectrum.

Probing new electroweak states via precision measurements at the LHC and future colliders (2019)
Journal Article

Several new physics scenarios, motivated e.g. by dark matter, feature new electroweakly charged states where the lightest particle in the multiplet is stable and neutral. In such cases direct searches at LHC are notoriously difficult, while electrowe... Read More about Probing new electroweak states via precision measurements at the LHC and future colliders.

Self-dual sectors for scalar field theories in (1 + 1) dimensions (2019)
Journal Article

We use ideas of generalized self-duality conditions to construct real scalar field theories in (1 + 1)-dimensions with exact self dual sectors. The approach is based on a pre-potential U that defines the topological charge and the potential energy of... Read More about Self-dual sectors for scalar field theories in (1 + 1) dimensions.

∆Ms theory precision confronts flavour anomalies (2019)
Journal Article

Based on recent HQET sum rule and lattice calculations we present updated Standard Model predictions for the mass differences of neutral B mesons: ΔMSMs=(18.4+0.7−1.2)ps−1 and ΔMSMd=(0.533+0.022−0.036)ps−1 study their impact onnew physics models that...

6d Conformal matter (2015)
Journal Article

A single M5-brane probing G, an ADE-type singularity, leads to a system which has G × G global symmetry and can be viewed as “bifundamental” (G, G) matter. For the A N series, this leads to the usual notion of bifundamental matter. For the other case... Read More about 6d Conformal matter.

Assessing perturbativity and vacuum stability in high-scale leptogenesis (2018)
Journal Article

We consider the requirements that all coupling constants remain perturbative and the electroweak vacuum metastable up to the Planck scale in high-scale thermal leptogenesis, in the context of a type-I seesaw mechanism. We find a large region of the m... Read More about Assessing perturbativity and vacuum stability in high-scale leptogenesis.

Fiducial distributions in Higgs and Drell-Yan production at N3LL+NNLO (2018)
Journal Article

The perturbative description of certain differential distributions across a wide kinematic range requires the matching of fixed-order perturbation theory with resummation of large logarithmic corrections to all orders. We present precise matched pred... Read More about Fiducial distributions in Higgs and Drell-Yan production at N3LL+NNLO.

Counting associatives in compact $G_2$ orbifolds (2019)
Journal Article

We describe a class of compact G2 orbifolds constructed from non-symplectic involutions of K3 surfaces. Within this class, we identify a model for which there are infinitely many associative submanifolds contributing to the effective superpotential o...

Higgs bundles for M-theory on G2-manifolds (2019)
Journal Article

M-theory compactified on G2-holonomy manifolds results in 4d N = 1 supersymmetric gauge theories coupled to gravity. In this paper we focus on the gauge sector of such compactifications by studying the Higgs bundle obtained from a partially twisted 7... Read More about Higgs bundles for M-theory on G2-manifolds.

Holographic thermodynamics of accelerating black holes (2018)
Journal Article

We present a careful study of accelerating black holes in anti-de Sitter spacetime, formulating the thermodynamics and resolving discrepancies that have appeared in previous investigations of the topic. We compute the dual stress-energy tensor for th... Read More about Holographic thermodynamics of accelerating black holes.

Yukawas and discrete symmetries in F-theory compactifications without section (2014)
Journal Article

In the case of F-theory compactifications on genus-one fibrations without section there are naturally appearing discrete symmetries, which we argue to be associated to geometrically massive U(1) gauge symmetries. These discrete symmetries are shown t... Read More about Yukawas and discrete symmetries in F-theory compactifications without section.
