Yang-Mills form factors on self-dual backgrounds

open access: yesJournal of High Energy Physics, 2023
The construction of perturbative quantities on non-linear backgrounds leads to the possibility of incorporating strong field effects in perturbation theory.

Nucleon form factors in QCD [PDF]

open access: yesPhysical Review D, 2006
We calculate the electromagnetic and the axial form factors of the nucleon within the framework of light cone sum rules (LCSR) to leading order in QCD and including higher twist corrections. In particular we motivate a certain choice for the interpolating nucleon field.

The Loschmidt spectral form factor

open access: yesJournal of High Energy Physics, 2022
Abstract The Spectral Form Factor (SFF) measures the fluctuations in the density of states of a Hamiltonian. We consider a generalization of the SFF called the Loschmidt Spectral Form Factor, $$ \textrm{tr}\left[{e}^{i{H}_1T}\right]\textrm{tr}\left[{e}^{-i{H}_2T}\right] $$ tr

INTERMOLECULAR POTENTIAL CURVES – «COMPANIONS» AND FORECAST ON THEIR BASIS OF THE CRITICAL PARAMETERS

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2019
An inflection point is entered in the description of the potential curve (PC). Taking into account the emerging possibilities, the potentials of Mi (n – 6) reduced by the properties of nine substances from globular molecules were analyzed.

Quark and Gluon Form Factors at Three Loops in Perturbative QCD [PDF]

open access: yes, 2009
We compute the quark and gluon form factors at up to three-loop order within massless perturbative Quantum Chromodynamics by studying the photon-quark-anti-quark vertex and the effective vertex of a Higgs boson and two gluons.

Fire as a Soil-Forming Factor [PDF]

open access: yesAMBIO, 2013
In the span of a human generation, fire can, in theory, impact all the land covered by vegetation. Its occurrence has many important direct and indirect effects on soil, some of which are long-lasting or even permanent. As a consequence, fire must be considered a soil-forming factor, on par with the others traditionally recognized, namely: parent ...

Harmony of super form factors [PDF]

open access: yesJournal of High Energy Physics, 2011
In this paper we continue our systematic study of form factors of half-BPS operators in N=4 super Yang-Mills. In particular, we extend various techniques known for amplitudes to the case of form factors, including MHV rules, recursion relations, unitarity and dual MHV rules. As an application, we present the solution of the recursion relation for split-
