Learning the language of QCD jets with transformers
Journal of High Energy Physics, 2023 Transformers have become the primary architecture for natural language processing. In this study, we explore their use for auto-regressive density estimation in high-energy jet physics, which involves working with a high-dimensional space.

Under-determination in Cosmology: an Invitation [PDF]
, 2012 I discuss how modern cosmology illustrates under-determination of theoretical hypotheses by data, in ways that are different from most philosophical discussions.

When Thriving for More Collapses the System: The Academic Reproduction of Uncaring Structures
British Journal of Management, EarlyView.Abstract This essay argues that the widening gap between aspirational aims and visionary orientations and the prevailing practices in neoliberal academia stems from deeper, historically rooted, market‐based logics shaping our institutions, increasingly governed by economic values and academic subjectivities therein.

Illustrated study of the semiholographic nonperturbative framework [PDF]
, 2017 Semiholography has been proposed as an effective nonperturbative framework which can consistently combine perturbative and nonperturbative effects for theories like QCD.

Weighing Cosmological Models with SNe Ia and Gamma Ray Burst Redshift Data
Universe, 2019 Many models have been proposed to explain the intergalactic redshift using different observational data and different criteria for the goodness-of-fit of a model to the data. The purpose of this paper is to examine several suggested models using the same

Accelerating cosmology in Rastall's theory
Il Nuovo Cimento B, 2009 In an attempt to look for a viable mechanism leading to a present-day accelerated expansion, we investigate the possibility that the observed cosmic speed up may be recovered in the framework of the Rastall's theory, relying on the non-conservativity of the stress-energy tensor, i.e. $T^μ_{ν; μ} \neq 0$.

Modulated reheating and large non-gaussianity in string cosmology [PDF]
, 2012 A generic feature of the known string inflationary models is that the same physics that makes the inflaton lighter than the Hubble scale during inflation often also makes other scalars this light.

The Big Picture: Religion and Global Comparative History
Journal of Religious History, EarlyView.This article considers what a ‘big picture’ approach to global religious history might look like, and in particular the implications of deploying the comparative method across much larger stretches of time and space than historians normally attend to. It will begin by reflecting on the epistemological moods that have hindered this project to date, the ...

Bounds on ALP-mediated dark matter models from celestial objects
Journal of High Energy PhysicsWe have studied the signals from axion-like particles (ALPs) as dark matter mediators from celestial objects such as neutron stars, brown dwarfs or white dwarfs.

The Flatness Problem and the Variable Physical Constants
Galaxies, 2019 We have used the varying physical constant approach to resolve the flatness problem in cosmology. Friedmann equations are modified to include the variability of speed of light, gravitational constant, cosmological constant, and the curvature constant ...
