Partially composite Higgs models: phenomenology and RG analysis [PDF]
Journal of High Energy Physics, 2018 We study the phenomenology of partially composite-Higgs models where electroweak symmetry breaking is dynamically induced, and the Higgs is a mixture of a composite and an elementary state.

Fermion mass splitting in the technicolor coupled scenario
European Physical Journal C: Particles and Fields, 2020 We discuss fermion mass generation in unified models where QCD and technicolor (or any two strongly interacting theories) have their Schwinger–Dyson equations coupled.

The W boson mass weighs in on the non-standard Higgs [PDF]
Physics Letters B, 2022 We consider the implications of the CDF collaboration high-precision measurement of the W boson mass on models with a non-standard Higgs. We show that this requires an enhancement of more than 5% in the non-standard Higgs coupling to the gauge bosons ...

Relaxation of the composite Higgs little hierarchy
Journal of High Energy Physics, 2017 We describe a composite Higgs scenario in which a cosmological relaxation mechanism naturally gives rise to a hierarchy between the weak scale and the scale of spontaneous global symmetry breaking.

Techni-composite Higgs models with symmetric and asymmetric dark matter candidates [PDF]
, 2021 International audienceWe propose a novel class of composite models that feature both a technicolor and a composite Higgs vacuum limit, resulting in an asymmetric dark matter candidate.

What is it like to be colour‐blind? A case study in experimental philosophy of experience
Mind &Language, Volume 37, Issue 5, Page 814-839, November 2022., 2022 What is the experience of someone who is “colour‐blind” like? This paper presents the results of a study that uses qualitative research methods to better understand the lived experience of colour blindness. Participants were asked to describe their experiences of a variety of coloured stimuli, both with and without EnChroma glasses—glasses which, the ...

High‐dimensional principal component analysis with heterogeneous missingness
Journal of the Royal Statistical Society: Series B (Statistical Methodology), Volume 84, Issue 5, Page 2000-2031, November 2022., 2022 Abstract We study the problem of high‐dimensional Principal Component Analysis (PCA) with missing observations. In a simple, homogeneous observation model, we show that an existing observed‐proportion weighted (OPW) estimator of the leading principal components can (nearly) attain the minimax optimal rate of convergence, which exhibits an interesting ...

Absence in technicolour: protesting enforced disappearances in northern Sri Lanka
Journal of the Royal Anthropological Institute, Volume 28, Issue S1, Page 118-134, April 2022., 2022 Abstract This essay examines the political uses of photography in the protests of the Tamil families of the disappeared in northern Sri Lanka. Enforced disappearances have long featured as an instrument of state terror. Their lingering effects have been noted as a significant challenge to transitional justice processes in the aftermath of the island's ...

String (Gravi)photons, “Dark Brane Photons”, Holography and the Hypercharge Portal
Fortschritte der Physik, Volume 69, Issue 6, June 2021., 2021 Abstract The mixing of graviphotons and dark brane photons to the Standard Model hypercharge is analyzed in full generality, in weakly‐coupled string theory. Both the direct mixing as well as effective terms that provide mixing after inclusion of SM corrections are estimated to lowest order.
