Colored Group Field Theory

, 2009
Group field theories are higher dimensional generalizations of matrix models. Their Feynman graphs are fat and in addition to vertices, edges and faces, they also contain higher dimensional cells, called bubbles.

Five-loop renormalisation of QCD in covariant gauges

Journal of High Energy Physics, 2017
We present the complete set of vertex, wave function and charge renormalisation constants in QCD in a general simple gauge group and with the complete dependence on the covariant gauge parameter ξ in the minimal subtraction scheme of conventional ...

Renormalization Group and Probability Theory

, 2000
The renormalization group has played an important role in the physics of the second half of the twentieth century both as a conceptual and a calculational tool.

Apollonian Circle Packings: Geometry and Group Theory I. The Apollonian Group [PDF]

, 2005
Apollonian circle packings arise by repeatedly filling the interstices between four mutually tangent circles with further tangent circles. We observe that there exist Apollonian packings which have strong integrality properties, in which all circles in ...

Exploring Preferences for a Digital Single‐Session Intervention for Adolescent Siblings of Youth With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Adolescent siblings of children with cancer are at elevated risk for psychosocial problems. Unfortunately, various barriers such as limited family time and resources, conflicting schedules, and psychosocial staffing constraints at cancer centers hinder sibling access to support.

A phenomenological analysis of LHC neutrino scattering at NLO accuracy matched to parton showers

European Physical Journal C: Particles and Fields
We perform a detailed phenomenological study of high-energy neutrino deep inelastic scattering (DIS) focused on LHC far-forward experiments such as FASER $$\nu $$ ν and SND@LHC.

Four-loop QCD propagators and vertices with one vanishing external momentum

Journal of High Energy Physics, 2017
We have computed the self-energies and a set of three-particle vertex functions for massless QCD at the four-loop level in the M S ¯ $$ \overline{\mathrm{MS}} $$ renormalization scheme.

EPRL/FK Group Field Theory

, 2010
The purpose of this short note is to clarify the Group Field Theory vertex and propagators corresponding to the EPRL/FK spin foam models and to detail the subtraction of leading divergences of the model.Comment: 20 pages, 2 ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Aspects of Group Field Theory

, 2012
I review the basic ingredients of discretized gravity which motivate the introduction of Group Field Theory. Thus I describe the GFT formulation of some models and conclude with a few remarks on the emergence of noncommutative structures in such models ...
