Homophily‐adjusted social influence estimation

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Homophily and social influence are two key concepts of social network analysis. Distinguishing between these phenomena is difficult, and approaches to disambiguate the two have been primarily limited to longitudinal data analyses. In this study, we provide sufficient conditions for valid estimation of social influence through cross‐sectional ...

Factorization and resummation for transverse thrust [PDF]

open access: yes, 2015
We analyze transverse thrust in the framework of Soft Collinear Effective Theory and obtain a factorized expression for the cross section that permits resummation of terms enhanced in the dijet limit to arbitrary accuracy.

TEMPERATURE RENORMALIZATION GROUP AND RESUMMATION [PDF]

open access: yesInternational Journal of Modern Physics A, 1993
The temperature renormalization group equation (TRGE) is compared with a diagrammatic expansion for the (ϕ4)4-theory. It is found that the one-loop TRGE resums the leading powers of temperature for the effective mass. A two-loop contribution to TRGE is required to do the leading resummation for the coupling constant.

Sudakov resummations at higher orders [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2006
We summarize our recent results on the resummation of hard-scattering coefficient functions and on-shell form factors in massless perturbative QCD. The threshold resummation has been extended to the fourth logarithmic order for deep-inelastic scattering, Drell-Yan lepton pair production and Higgs production via gluon-gluon fusion.

Large parameter asymptotic analysis for homogeneous normalized random measures with independent increments

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Homogeneous normalized random measures with independent increments represent a broad class of Bayesian nonparametric priors and thus are widely used. In this article, we obtain the strong law of large numbers, the central limit theorem (CLT), and the functional central limit theorem (fCLT) of such measures when the concentration parameter a ...

Threshold resummation of rapidity distributions at fixed partonic rapidity

open access: yesJournal of High Energy Physics
We derive a general expression for the resummation of rapidity distributions for processes with a colorless final state, such as Drell-Yan or Higgs production, in the limit in which the center-of-mass energy goes on threshold, but with fixed rapidity of ...

HIGH ENERGY RESUMMATION IN PERTURBATIVE QCD [PDF]

open access: yes, 2010
In this work, we review the general aspects of the high energy resummation technique. Recently derived results for high energy resummation of direct photon production are matched to NLO computations, and their implications at the Tevatron and at the ...

Electroweak resummation of neutralino dark-matter annihilation into high-energy photons

open access: yes, 2022
We consider the resummation of large electroweak Sudakov logarithms for the annihilation of neutralino DM with (TeV) mass to high-energy photons in the minimal supersymmetric standard model, extending previous work on the minimal wino and Higgsino models.
