Dissipation in holographic superfluids (2021)
Journal Article

We study dissipation in holographic superfluids at finite temperature and zero chemical potential. The zero overlap with the heat current allows us to isolate the physics of the conserved current corresponding to the broken global U(1). By using anal...

Dynamics of diffractive dissociation (2021)
Journal Article

We describe a QCD based model which incorporates the main properties of the inclusive particle distributions expected for diffractive processes, including the diffractive dissociation at high energies. We study, in turn, the total cross section, σtot... Read More about Dynamics of diffractive dissociation.

Determining the lifetime of long-lived particles at the HL-LHC (2021)
Journal Article

We examine the capacity of the Large Hadron Collider to determine the mean proper lifetime of long-lived particles assuming different decay final states. We mostly concentrate on the high luminosity runs of the LHC, and therefore, develop our discuss... Read More about Determining the lifetime of long-lived particles at the HL-LHC.

Resurgent expansion of Lambert series and iterated Eisenstein integrals (2021)
Journal Article

We consider special Lambert series as generating functions of divisor sums and determine their complete transseries expansion near rational roots of unity. Our methods also yield new insights into the Laurent expansions and modularity properties of i... Read More about Resurgent expansion of Lambert series and iterated Eisenstein integrals.

Yang-Baxter deformations of the principal chiral model plus Wess-Zumino term (2020)
Journal Article

A large class of integrable deformations of the principal chiral model, known as the Yang–Baxter deformations, are governed by skew-symmetric R-matrices solving the (modified) classical Yang–Baxter equation. We carry out a systematic investigation of... Read More about Yang-Baxter deformations of the principal chiral model plus Wess-Zumino term.

Searching for QCD instantons at hadron colliders (2021)
Journal Article

QCD instantons are arguably the best motivated yet unobserved nonperturbative effects predicted by the Standard Model. A discovery and detailed study of instanton-generated processes at colliders would provide a new window into the phenomenological e...

Instanton worldlines in five-dimensional Ω-deformed gauge theory (2021)
Journal Article

We discuss the Bosonic sector of a class of supersymmetric non-Lorentzian five-dimensional gauge field theories with an SU(1,3) conformal symmetry. These actions have a Lagrange multiplier which imposes a novel Ω-deformed anti-self-dual gauge field c... Read More about Instanton worldlines in five-dimensional Ω-deformed gauge theory.

Supersymmetric solitons and a degeneracy of solutions in AdS/CFT (2021)
Journal Article

We study Lorentzian supersymmetric configurations in D = 4 and D = 5 gauged N = 2 supergravity. We show that there are smooth 1/2 BPS solutions which are asymptotically AdS4 and AdS5 with a planar boundary, a compact spacelike direction and with a Wi...

The Standard Model quiver in de Sitter string compactifications (2021)
Journal Article

We argue that the Standard Model quiver can be embedded into compact Calabi-Yau geometries through orientifolded D3-branes at del Pezzo singularities dPn with n ≥ 5 in a framework including moduli stabilisation. To illustrate our approach, we explici... Read More about The Standard Model quiver in de Sitter string compactifications.

Thermodynamics of Many Black Holes (2021)
Journal Article

We discuss the thermodynamics of an array of collinear black holes which may be accelerating. We prove a general First Law, including variations in the tensions of strings linking and accelerating the black holes. We analyse the implications of the F...

EFT diagrammatica: UV roots of the CP-conserving SMEFT (2021)
Journal Article

The Standard Model Effective Field Theory (SMEFT) is an established theoretical framework that parametrises the impact a UV theory has on low-energy observables. Such parametrization is achieved by studying the interactions of SM fields encapsulated... Read More about EFT diagrammatica: UV roots of the CP-conserving SMEFT.

D Solar neutrino probes of the muon anomalous magnetic moment in the gauged U(1) L-mu-L-tau (2020)
Journal Article

Models of gauged U(1)Lμ−Lτ can provide a solution to the long-standing discrepancy between the theoretical prediction for the muon anomalous magnetic moment and its measured value. The extra contribution is due to a new light vector mediator, which a... Read More about D Solar neutrino probes of the muon anomalous magnetic moment in the gauged U(1) L-mu-L-tau.

JUNE: open-source individual-based epidemiology simulation (2021)
Journal Article

We introduce June, an open-source framework for the detailed simulation of epidemics on the basis of social interactions in a virtual population constructed from geographically granular census data, reflecting age, sex, ethnicity and socio-economic i...

Combine and conquer: event reconstruction with Bayesian Ensemble Neural Networks (2021)
Journal Article

Ensemble learning is a technique where multiple component learners are combined through a protocol. We propose an Ensemble Neural Network (ENN) that uses the combined latent-feature space of multiple neural network classifiers to improve the represen...

Analytic results for scalar-mediated Higgs boson production in association with two jets (2021)
Journal Article

We present compact analytic formulae for all one-loop amplitudes representing the production of a Higgs boson in association with two jets, mediated by a colour triplet scalar particle. Many of the integral coefficients present for scalar mediators a... Read More about Analytic results for scalar-mediated Higgs boson production in association with two jets.

Creation and observation of Hopfions in magnetic multilayer systems (2021)
Journal Article

Among topological solitons, magnetic skyrmions are two-dimensional particle-like objects with a continuous winding of the magnetization, and magnetic Hopfions are three-dimensional objects that can be formed from a closed loop of twisted skyrmion str...

Scale and isolation sensitivity of diphoton distributions at the LHC (2021)
Journal Article

Precision measurements of diphoton distributions at the LHC display some tension with theory predictions, obtained at next-to-next-to-leading order (NNLO) in QCD. We revisit the theoretical uncertainties arising from the approximation of the experime... Read More about Scale and isolation sensitivity of diphoton distributions at the LHC.
