The MOLLER Experiment

The MOLLER experiment will measure the weak charge of the electron, $Q^e_W = 1 - 4\sin^2\theta_W$, with a precision of 2.3% by measuring the parity-violating asymmetry in electron-electron (M\oller) scattering. This measurement will provide an ultra-precise measurement of the weak mixing angle, $\sin^2\theta_W$, which is on par with the two most precise collider measurements at the Z$^0$-pole. The precision of the experiment, with a fractional accuracy in the determination of $\sin^2\theta_W$ $\approx 0.1$%, makes it a probe of physics beyond the Standard Model with sensitivities to mass scales of new physics up to 7.5 TeV.Comment: Proceedings from PAVI 11 to be published in Nuovo Cimento

Conley Index at Infinity

The aim of this paper is to explore the possibilities of Conley index techniques in the study of heteroclinic connections between finite and infinite invariant sets. For this, we remind the reader of the Poincar\'e compactification: this transformation allows to project a $n$-dimensional vector space $X$ on the $n$-dimensional unit hemisphere of $X\times \mathbb{R}$ and infinity on its $(n-1)$-dimensional equator called the sphere at infinity. Under normalizability condition, vector fields on $X$ transform into vector fields on the Poincar\'e hemisphere whose associated flows let the equator invariant. The dynamics on the equator reflects the dynamics at infinity, but is now finite and may be studied by Conley index techniques. Furthermore, we observe that some non-isolated behavior may occur around the equator, and introduce the concept of invariant sets at infinity of isolated invariant dynamical complement. Through the construction of an extended phase space together which an extended flow, we are able to adapt the Conley index techniques and prove the existence of connections to such non-isolated invariant sets.Comment: 25 pages, 8 figure

Eco-innovation opportunities in the waste management sector in Scotland

Creating more circular economies that retain and recirculate the value of resources within an economy is gaining significant attention, with the concept of industrial symbiosis assisting businesses to reduce resource leakage from local economies. An eco-industrial park applies industrial symbiosis on the scale of an industrial park and may incorporate additional features such as shared infrastructure and services that assist in reducing environmental impacts and improving resource efficiency. This paper provides an overview of the application of the industrial symbiosis concept in Scotland and presents findings of the ACE Eco-Partnerships project, which attempted to identify and develop opportunities for industrial symbiosis in the Tayside and Fife region of Scotland, particularly on the scale of eco-industrial parks. The paper provides reflection on some of the barriers to eco-industrial park development, with specific reference to “retrofitting” industrial symbiosis onto existing industrial parks versus developing new eco-industrial parks
