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.

Discriminating between technicolor and warped extra dimensional model via pp → ZZ channel [PDF]
, 2009 We explore the possibility to discriminate between certain strongly coupled technicolor (TC) models and warped extra dimensional models where the standard model fields are propagating in the extra dimension.

Light composite scalar boson from a see-saw mechanism in two-scale TC models
Physics Letters B, 2015 We consider the possibility of a light composite scalar boson arising from mass mixing between a relatively light and heavy scalar singlets in a see-saw mechanism expected to occur in two-scale Technicolor (TC) models.

Composite Higgs at high transverse momentum
Journal of High Energy Physics, 2020 In this paper we explore composite Higgs scenarios through the effects of light top-partners in Higgs+Jet production at the LHC. The pseudo-Goldstone boson nature of the Higgs field means that single-Higgs production via gluon fusion is insensitive to ...

A more natural composite Higgs model
Journal of High Energy Physics, 2020 Composite Higgs models provide an attractive solution to the hierarchy problem. However, many realistic models suffer from tuning problems in the Higgs potential. There are often large contributions from the UV dynamics of the composite resonances to the

Deciphering the minimum of energy of some walking technicolor models [PDF]
, 2010 There are quasiconformal theories, like the minimal and ultraminimal technicolor models, which may break dynamically the gauge symmetry of the standard model and at the same time are compatible with electroweak precision data.

Phenomenology of flavorful composite vector bosons in light of B anomalies
Journal of High Energy Physics, 2017 We analyze the flavor structure of composite vector bosons arising in a model of vectorlike technicolor — often called hypercolor (HC) — with eight flavors that form a one-family content of HC fermions.
