Exclusive J/ψ and ϒ production in high-energy pp and p-Pb collisions (2022)
Journal Article

We present a formalism for determining the cross section for exclusive heavy vector meson production (J/ψ,Υ) as a function of rapidity, in both high-energy proton-proton and proton-heavy ion collisions, at next-to-leading order in QCD. We compare and... Read More about Exclusive J/ψ and ϒ production in high-energy pp and p-Pb collisions.

Supersymmetric solitons in gauged N $$ \mathcal{N} $$ = 8 supergravity (2023)
Journal Article

We consider soliton solutions in AdS4 with a flat slicing and Wilson loops around one cycle. We study the phase structure and find the ground state and identify supersymmetric solutions as a function of the Wilson loops. We work in the context of a s...

Cosmologies inside hyperbolic black holes (2022)
Journal Article

Models with closed FRW cosmologies on the worldvolume of a constant-tension brane inside a black hole provide an interesting setup for studying cosmology holographically. However, in more than two worldvolume dimensions, there are limitations on such... Read More about Cosmologies inside hyperbolic black holes.

Holographic dissipation from the symplectic current (2022)
Journal Article

We develop analytic techniques to construct the leading dissipative terms in a derivative expansion of holographic fluids. Our basic ingredient is the Crnkovic-Witten symplectic current of classical gravity which we use to extract the dissipative tra...

Cosmic Inflation and Genetic Algorithms (2022)
Journal Article

Large classes of standard single-field slow-roll inflationary models consistentwith the required number of e-folds, the current bounds on the spectral indexof scalar perturbations, the tensor-to-scalar ratio, and the scale of inflation canbe efficien...

New Higgs decays to axion-like particles (2022)
Journal Article

We investigate the interactions of a light scalar with the Higgs boson and second-generation fermions, which trigger new rare decays of the Higgs boson into 4μ, 2μ2γ , 6μ and 4μ2 j. We recast current LHC searches to constrain these decays and develop... Read More about New Higgs decays to axion-like particles.

Modular graph forms from equivariant iterated Eisenstein integrals (2022)
Journal Article

The low-energy expansion of closed-string scattering amplitudes at genus one introduces infinite families of non-holomorphic modular forms called modular graph forms. Their differential and number-theoretic properties motivated Brown’s alternative co... Read More about Modular graph forms from equivariant iterated Eisenstein integrals.

Collider events on a quantum computer (2022)
Journal Article

An intuitive definition of the partonic flavor of a jet in quantum chromodynamics is often only well-defined in the deep ultraviolet, where the strong force becomes a free theory and a jet consists of a single parton. However, measurements are perfor... Read More about Collider events on a quantum computer.

Coloring mixed QCD/QED evolution (2022)
Journal Article

Parton showers are crucial components of high-energy physics calculations. Improving their modelling of QCD is an active research area since shower approximations are stumbling blocks for precision event generators. Naively, the interference between...

Enhanced soft limits in de Sitter space (2022)
Journal Article

In flat space, the scattering amplitudes of certain scalar effective field theories exhibit enhanced soft limits due to the presence of hidden symmetries. In this paper, we show that this phenomenon extends to wavefunction coefficients in de Sitter s... Read More about Enhanced soft limits in de Sitter space.

Multikink scattering in the ϕ6 model revisited (2022)
Journal Article

Antikink-kink (KK) collisions in the ¯ ϕ6 model exhibit resonant scattering although the ϕ6 kinks do not support any bound states to which energy could be transferred. In P. Dorey et al. [Kink-Antikink Collisions in the ϕ6 Model, Phys. Rev. Lett. 107... Read More about Multikink scattering in the ϕ6 model revisited.

Quantum walk approach to simulating parton showers (2022)
Journal Article

This paper presents a novel quantum walk approach to simulating parton showers on a quantum computer. We demonstrate that the quantum walk paradigm offers a natural and more efficient approach to simulating parton showers on quantum devices, with the...

Branes and Non‐Invertible Symmetries (2022)
Journal Article

=4 supersymmetric Yang-Mills theories with algebra𝔰𝔬(4N) and appropriate choices of global structure can have non-invertible symmetries. We identify the branes holographically dual to the non-invertible symmetries, and derive the fusion rules for th... Read More about Branes and Non‐Invertible Symmetries.

Mean string field theory: Landau-Ginzburg theory for 1-form symmetries (2022)
Journal Article

By analogy with the Landau-Ginzburg theory of ordinary zero-form symmetries, we introduce and develop a Landau-Ginzburg theory of one-form global symmetries, which we call mean string field theory. The basic dynamical variable is a string field – def... Read More about Mean string field theory: Landau-Ginzburg theory for 1-form symmetries.

YFS Resummation for Future Lepton-Lepton Colliders in SHERPA (2022)
Journal Article

We present an implementation of the Yennie–Frautschi–Suura (YFS) scheme for the all orders resummation of logarithms from the emission of soft real and virtual photons in processes that are critical for future lepton colliders. They include, in parti... Read More about YFS Resummation for Future Lepton-Lepton Colliders in SHERPA.

New recursion relations for tree-level correlators in anti–de Sitter spacetime (2022)
Journal Article

We present for the first time classical multiparticle solutions in anti–de Sitter space (AdS) involving scalars, gluons, and gravitons. They are recursively defined through multiparticle currents which reduce to Berends-Giele currents in the flat spa...

Journal Article

We derive the leading dissipative corrections of holographic superfluids at finite temperature and chemical potential by employing our recently developed techniques to study dissipative effects in the hydrodynamic limit of holographic theories. As pa... Read More about Dissipative effects in finite density holographic superfluids.

The gaugino condensate from asymmetric four-torus with twists (2022)
Journal Article

We calculate the gaugino condensate in SU(2) super Yang-Mills theory on an asymmetric four-torus 𝕋4 with ’t Hooft’s twisted boundary conditions. The 𝕋4 asymmetry is controlled by a dimensionless detuning parameter ∆, proportional to L3L4 − L1L2, with... Read More about The gaugino condensate from asymmetric four-torus with twists.

Journal Article

Various features of the even order poles appearing in the S-matrices of simply-laced affine Toda field theories are analysed in some detail. In particular, the coefficients of first- and second-order singularities appearing in the Laurent expansion o...
