A formalism for the systematic treatment of rapidity logarithms in Quantum Field Theory

- J. Chiu, A. Jain, D. Neill, I. Rothstein
- Physics
- 3 February 2012

A bstractMany observables in QCD rely upon the resummation of perturbation theory to retain predictive power. Resummation follows after one factorizes the cross section into the relevant modes. The… Expand

Parton fragmentation within an identified jet at NNLL

- A. Jain, M. Procura, W. Waalewijn
- Physics
- 25 January 2011

The fragmentation of a light parton i to a jet containing a light energetic hadron h, where the momentum fraction of this hadron as well as the invariant mass of the jet is measured, is described by… Expand

Rapidity renormalization group.

- J. Chiu, A. Jain, D. Neill, I. Rothstein
- Physics, Medicine
- Physical review letters
- 5 April 2011

We introduce a systematic approach for the resummation of perturbative series which involves large logarithms not only due to large invariant mass ratios but large rapidities as well. A series of… Expand

Two-loop jet function and jet mass for top quarks

- A. Jain, I. Scimemi, I. Stewart
- Physics
- 7 January 2008

We compute the two-loop heavy-quark jet function in the heavy-quark limit. This is one of the key ingredients in next-to-next-to-leading order and next-to-next-to-leading-log order computations of… Expand

The MSR mass and the OΛQCD$$ \mathcal{O}\left({\Lambda}_{\mathrm{QCD}}\right) $$ renormalon sum rule

- A. Hoang, A. Jain, +4 authors I. Stewart
- Physics
- 5 April 2017

A bstractWe provide a detailed description and analysis of a low-scale short-distance mass scheme, called the MSR mass, that is useful for high-precision top quark mass determinations, but can be… Expand

Fully-unintegrated parton distribution and fragmentation functions at perturbative k⊥

- A. Jain, M. Procura, W. Waalewijn
- Physics
- 4 October 2011

A bstractWe define and study the properties of generalized beam functions (BFs) and fragmenting jet functions (FJFs), which are fully-unintegrated parton distribution functions (PDFs) and… Expand

Infrared renormalization-group flow for heavy-quark masses.

- A. Hoang, A. Jain, I. Scimemi, I. Stewart
- Physics, Medicine
- Physical review letters
- 31 March 2008

A short-distance heavy-quark mass depends on two parameters: the renormalization scale mu and a scale R controlling the absorption of infrared fluctuations. The radius for perturbative corrections… Expand

R evolution: Improving perturbative QCD

- A. Hoang, A. Jain, I. Scimemi, I. Stewart
- Physics
- 23 August 2009

Perturbative QCD results in the MS scheme can be dramatically improved by switching to a scheme that accounts for the dominant power law dependence on the factorization scale in the operator product… Expand

One-loop Angularity Distributions with Recoil using Soft-Collinear Effective Theory

- Ankita Budhraja, A. Jain, M. Procura
- Physics
- 26 March 2019

Angularities are event shapes whose sensitivity to the splitting angle of a collinear emission is controlled by a continuous parameter $b$, with $ -1 < b < \infty$. When measured with respect to the… Expand

Synthesis and E.P.R. Spectra of Randomly Oriented Molecules in Some Bis(Thiosemicarbazonato)copper(II) Complexes

- A. Jain, K. Pandeya
- Chemistry
- 1994

Abstract The synthesis and e.p.r. spectra of some bis(thiosemicarbazonato)copper(II) complexes in the polycrystalline state have been described. For the complexes derived from thiosemicarbazones of… Expand
