(π0,η,η’) mass splittings and mixings

A particularly challenging topic in the phenomenological study of QCD is the (π0,η,η’) particle mass splittings and mixings. With exact SU(3) flavour symmetry of the u, d and s quarks,...

Composite Higgs Phenomenology at the LHC

Understanding the nature of the Standard Model Higgs boson is still an open problem. An appealing possibility is that the Higgs boson be a composite particle resulting from a novel...

Decays of an exotic 1-+ hybrid meson resonance in QCD

Using cutting-edge lattice Quantum Chromodynamics (QCD) methods, in a recent calculation [Phys. Rev. D103, 054502 (2021), arXiv:2009.10034] we demonstrated the presence of an exotic hybrid meson resonance for the first...

Exoplanet Science at Imperial

Project – Exoplanet Demographics In recent years, a bimodal distribution has been observed in the sizes of small, close-in exoplanets, often referred to as the ‘radius gap’. Currently there are two...

Fundamental Physics from Strong Gravity

This project continues our work to characterise the behaviour of light fields in strong gravity environments, in particular focussing on the potential for gravitational wave signatures from dark matter, exotic...

HPQCD: the charming strangeness of the W boson

Theorists in the HPQCD collaboration have pinned down Vcs, a key parameter of the Standard Model, using STFC’s DIRAC Data Intensive supercomputer at Cambridge. Vcs is determined from combining the...

Nested sampling beyond Bayesian statistics

Nested sampling is a numerical tool widely used in cosmology for performing Bayesian data analysis: using astrophysical data and models of the universe to extract parameters such as its age...

Quantum Electrodynamics meets Quantum Chromodynamics

The Standard Model (SM) of Elementary Particles has been extremely successful in correctly predicting and describing the properties of elementary particles studied at experimental facilities all around the world. The...

The Occam’s razor equation

This equation is science in a nutshell. On the left-hand-side it has the Bayesian Evidence. This is the quantity which is responsible for updating our belief in a scientific model...
