WIMP-nucleus scattering in chiral effective theory

- Vincenzo Cirigliano, Michael Lawrence Graesser, Grigory Ovanesyan
- Physics
- 11 May 2012

A bstractWe discuss long-distance QCD corrections to the WIMP-nucleon(s) interactions in the framework of chiral effective theory. For scalar-mediated WIMP-quark interactions, we calculate all the… Expand

Dark force detection in low energy e-p collisions

- M. Freytsis, G. Ovanesyan, J. Thaler
- Physics
- 16 September 2009

We study the prospects for detecting a light boson X with mass mX ≾ 100 MeV at a low energy electron-proton collider. We focus on the case where X dominantly decays to e+e− as motivated by recent… Expand

Heavy dark matter annihilation from effective field theory.

- G. Ovanesyan, T. Slatyer, I. Stewart
- Physics, Medicine
- Physical review letters
- 29 September 2014

We formulate an effective field theory description for SU(2)_{L} triplet fermionic dark matter by combining nonrelativistic dark matter with gauge bosons in the soft-collinear effective theory. For a… Expand

Jet Quenching from QCD Evolution

- Yang-Ting Chien, A. Emerman, Z. Kang, G. Ovanesyan, I. Vitev
- Physics
- 9 September 2015

Recent advances in soft-collinear eective theory with Glauber gluons have led to the development of a new method that gives a unied description of inclusive hadron pro- duction in reactions with… Expand

Angular distributions of higher order splitting functions in the vacuum and in dense QCD matter

- Michael Fickinger, G. Ovanesyan, I. Vitev
- Physics
- 11 April 2013

A bstractWe study the collinear splitting functions needed for next-to-next-to-leading order calculations of jet production in the vacuum and in dense QCD matter. These splitting functions describe… Expand

On Glauber modes in soft-collinear effective theory

- C. Bauer, Bjorn O. Lange, G. Ovanesyan
- Physics
- 5 October 2010

Gluon interactions involving spectator partons in collisions at hadronic machines are investigated. We find a class of examples in which a mode, called Glauber gluons, must be introduced to the… Expand

One-loop correction to heavy dark matter annihilation

- G. Ovanesyan, N. Rodd, T. Slatyer, I. Stewart
- Physics
- 14 December 2016

We calculate the one-loop corrections to TeV scale dark matter annihilation in a model where the dark matter is described by an SU(2)$_L$ triplet of Majorana fermions, such as the wino. We use this… Expand

Infrared safety in factorized hard scattering cross-sections

- A. Hornig, C. Lee, G. Ovanesyan
- Physics
- 14 January 2009

Abstract The rules of soft-collinear effective theory can be used naively to write hard scattering cross-sections as convolutions of separate hard, jet, and soft functions. One condition required to… Expand

Effective predictions of event shapes: factorized, resummed and gapped angularity distributions

- A. Hornig, C. Lee, G. Ovanesyan
- Physics
- 26 January 2009

Using soft-collinear effective theory (SCET), which provides a unified framework for factorization, resummation of logarithms, and incorporation of universal nonperturbative functions in… Expand

An effective theory for jet propagation in dense QCD matter: jet broadening and medium-induced bremsstrahlung

- G. Ovanesyan, I. Vitev
- Physics
- 5 March 2011

Two effects, jet broadening and gluon bremsstrahlung induced by the propagation of a highly energetic quark in dense QCD matter, are reconsidered from effective theory point of view. We modify the… Expand
