A search for an excited muon decaying to a muon and two jets in pp collisions at √ s = 8 TeV with the ATLAS detector
(IOP Publishing: Open Access Journals, 20160731)© 2016 CERN for the benefit of the ATLAS Collaboration.Anew search signature for excited leptons is explored. Excited muons are sought in the channel pp → μμ∗→ μμ jet jet, assuming both the production and decay occur via ... 
A surprise in the amplitude/Wilson loop duality
(20100429)One of the many remarkable features of MHV scattering amplitudes is their conjectured equality to lightlike polygon Wilson loops, which apparently holds at all orders in perturbation theory as well as nonperturbatively. ... 
ABJM amplitudes and the positive orthogonal Grassmannian
(Springer, 20140225)A remarkable connection between perturbative scattering amplitudes of four dimensional planar SYM, and the stratification of the positive Grassmannian, was revealed in the seminal work of ArkaniHamed et al. Similar extension ... 
An Action for Ftheory: SL(2)×R+SL(2)×R+ Exceptional Field Theory
(IOP Publishing: Hybrid Open Access, 201609)We construct the 12dimensional exceptional field theory (EFT) associated to the group SL(2)×R+SL(2)×R+. Demanding the closure of the algebra of local symmetries leads to a constraint, known as the section condition, that ... 
All rational oneloop EinsteinYangMills amplitudes at four points
(Springer, 201809)All fourpoint mixed gluongraviton amplitudes in pure EinsteinYangMills theory with at most one state of negative helicity are computed at oneloop order and maximal powers of the gauge coupling, using Ddimensional ... 
Analytic twoloop form factors in N=4 SYM

Asymptoticallyflat supergravity solutions deep inside the blackhole regime
(Springer, 20180201)We construct an infinite family of smooth asymptoticallyflat supergravity solutions that have the same charges and angular momenta as general supersymmetric D1D5P black holes, but have no horizon. These solutions resemble ... 
Charge transport by holographic Fermi surfaces
(American Physical Society, 201308)We compute the contribution to the conductivity from holographic Fermi surfaces obtained from probe fermions in an AdS charged black hole. This requires calculating a certain part of the oneloop correction to a vector ... 
Chargedparticle distributions in s=13 TeV pp interactions measured with the ATLAS detector at the LHC
(20160710)© 2016 CERN for the benefit of the ATLAS Collaboration.Chargedparticle distributions are measured in protonproton collisions at a centreofmass energy of 13 TeV, using a data sample of nearly 9 million events, corresponding ... 
Chiral Ring Generating Functions & Branches of Moduli Space
(201507)We consider the worldvolume theory of N D3branes transverse to various noncompact CalabiYau spaces, and describe subtleties in the counting of chiral primary operators in such theories due to the presence of multiple ... 
Combination of searches for WW, WZ, and ZZ resonances in pp collisions at s=8 TeV with the ATLAS detector
(20160410)© 2016 CERN for the benefit of the ATLAS Collaboration.The ATLAS experiment at the CERN Large Hadron Collider has performed searches for new, heavy bosons decaying to WW, WZ and ZZ final states in multiple decay channels ... 
Conformal manifolds in four dimensions and chiral algebras
(IOP Publishing: Hybrid Open Access, 201605)Any N = 2 superconformal field theory (SCFT) in four dimensions has a sector of operators related to a twodimensional chiral algebra containing a Virasoro subalgebra. Moreover, there are wellknown examples of isolated ... 
Constraints on chiral operators in N=2 SCFTs
(Springer Verlag, 2014)Abstract: We study certain higherspin chiral operators in (formula presented)(formula presented) superconformal field theories (SCFTs). In Lagrangian theories, or in theories related to Lagrangian theories by generalized ...

Continuous Tuning of Organic Phosphorescence by Diluting Triplet Diffusion at the Molecular Level.
(American Chemical Society, 201804)Organic longpersistent phosphorescent materials are advantageous due to the costeffectiveness and easy processability. The organic phosphorescence is achieved by the longlived triplet excitons, and the challenges are ... 
Cosmology on all scales: A twoparameter perturbation expansion
(American Physical Society, 201702)We propose and construct a twoparameter perturbative expansion around a FriedmannLemaîtreRobertsonWalker geometry that can be used to model highorder gravitational effects in the presence of nonlinear structure. This ... 
Counting Tensor Model Observables and Branched Covers of the 2Sphere
(2014)Lattice gauge theories of permutation groups with a simple topological action (henceforth permutationTFTs) have recently found several applications in the combinatorics of quantum field theories (QFTs). They have been ...
