Extra-dimensional Origins of Chemical Potentials at the Cosmological Collider
Raman Sundrum, Zhaohui Xu
We study the realization of the chemical potential mechanism in cosmological collider physics in a robust class of inflationary models arising from multiple higher-dimensional gaug…
Energy Correlators in Warped Geometries
Lorenzo Ricci, Raman Sundrum
We study Energy Correlators as probes of strongly-coupled nearly-conformal field theories within their holographically dual descriptions, focusing on the important features that ap…
Charged Loops at the Cosmological Collider with Chemical Potential
Arushi Bodas, Edward Broadberry, Raman Sundrum +1
Cosmological collider physics allows the detection of heavy particles at inflationary scales through their imprints on primordial non-Gaussianities. We study the chemical potential…
Partial Compositeness: from Anarchy to Symmetry
Kaustubh Agashe, Lorenzo Ricci, Raman Sundrum
Within the Composite Higgs paradigm, Partial Compositeness has emerged as an elegant mechanism for generating large flavor hierarchies such as are observed in the quark and lepton…
