Global Structure of Curves from Generalized Unitarity Cut of Three-loop Diagrams

This paper studies the global structure of algebraic curves defined by generalized unitarity cut of four-dimensional three-loop diagrams with eleven propagators. The global structure is a topological invariant that is characterized by the geometric genus of the algebraic curve. We use the Riemann-Hurwitz formula to compute the geometric genus of algebraic curves with the help of techniques involving convex hull polytopes and numerical algebraic geometry. Some interesting properties of genus for arbitrary loop orders are also explored where computing the genus serves as an initial step for integral or integrand reduction of three-loop amplitudes via an algebraic geometric approach.Comment: 35pages, 10 figures, version appeared in JHE

“That They All Might Be One”: John R. Mott’s Contributions to Methodism, Interreligious Dialogue, and Racial Reconciliation

An extraordinary organizer and leader, Methodist layman John R. Mott (1865–1955) was influential in the establishment and growth of many different world-wide Christian organizations in the early twentieth century. He was even asked to serve as ambassador to China by President Woodrow Wilson—a position he declined. For his work in organizing people and resources for world peace Mott was awarded the Nobel Peace Prize in 1946. This article focuses on Mott’s efforts at ecumenism for the sake of Christian mission by analyzing three dimensions of Mott’s work: Mott’s Methodism, his efforts in global interreligious dialogue, and work in racial reconciliation efforts at the end of the nineteenth and beginning of the twentieth centuries. His work in relation to these three themes is traced through out his life in order to highlight the development of his ideas and activism as he inter acted with many different ecumenical organizations and world Christian leaders. The article illustrates the tensions and inconsistencies that emerged in Mott’s thinking and ecumenical practice as he sought to emphasize unity for the sake of mission in the many different facets of his work

QCD Amplitudes: new perspectives on Feynman integral calculus

I analyze the algebraic patterns underlying the structure of scattering amplitudes in quantum field theory. I focus on the decomposition of amplitudes in terms of independent functions and the systems of differential equations the latter obey. In particular, I discuss the key role played by unitarity for the decomposition in terms of master integrals, by means of generalized cuts and integrand reduction, as well as for solving the corresponding differential equations, by means of Magnus exponential series.Comment: Presented at Rencontres de Moriond 201

Introduction by Professor Virginia Berridge, London School of Hygiene and Tropical MedicineThe World Health Organization (WHO)’s Framework Convention on Tobacco Control (FCTC) is the first global convention on public health. Comprehensive tobacco control had been the subject of 20 resolutions – consensus statements of all the member states – passed by the World Health Assembly beginning in 1970. This was 20 years after Sir Richard Doll and Sir Austin Bradford Hill suggested a link between smoking and cancer. The idea of a legally binding international convention, proposed by the late Dr Ruth Roemer and supported by a report from Dr Judith Mackay, was given priority by the new WHO Director-General Dr Gro Brundtland in 1998 when she elevated tobacco control as one of WHO’s three flagship programmes and created the Tobacco Free Initiative. The idea took wing with the publication of a review of tobacco company strategies to undermine tobacco control activities at WHO, which drew on 13 million documents released by the US courts to the public in 1998. This Witness Seminar, held in Geneva on the fifth anniversary of the WHO FCTC in 2010, heard from key individuals actively involved with the treaty negotiations, held between 2000 and 2003, and which came into force on 27 February 2005.The History of Modern Biomedicine Research Group is funded by the Wellcome Trust, which is a registered charity, no. 210183
