The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV measured properties compatible those Standard-Model Higgs boson, coupled absence discoveries phenomena beyond Standard Model at TeV scale, has triggered interest in ideas for future factories. A circular e+e- collider hosted 80 to 100 km tunnel, TLEP, is among most attractive solutions proposed so far. It clean experimental environment, produces high luminosity top-quark, W Z studies, accommodates multiple...

This report summarizes the activities of SM and NLO Multileg Working Group Workshop "Physics at TeV Colliders", Les Houches, France 8-26 June, 2009.
The 2011 Les Houches workshop was the first to confront LHC data. In two years since previous there have been significant advances in both soft and hard QCD, particularly areas of multi-leg NLO calculations, inclusion those calculations into parton shower Monte Carlos, tuning non-perturbative parameters Carlos. These proceedings describe theoretical that taken place, impact early data, for future development.
Muography (or muon radiography) is a technique that exploits the penetration capability of muons, elementary particles similar to electrons but with mass about 200 times larger. High energy muons are naturally produced in interactions cosmic rays Earth atmosphere. The measurement their absorption matter allows imaging inner structure large bodies. technological developments detection have opened way its application various fields, such as archaeology, studies geological structures, civil...
Transmission muography is an imaging technique that allows us to obtain two-dimensional and three-dimensional average-target density images by measuring the transmission of atmospheric muons. Through this technique, it possible observe anomalies inside a target volume locate them three-dimensionally. In work, potential will be illustrated through description results two measurements carried out in tourist path Temperino mine (Livorno, Italy) area where higher concentration Radon gas...

Animal burrows in a river's earthen levee leads to water piping phenomena causing structural damage and eventual collapse during floods. Currently, the state of art comprises case studies that deal with management maintenance, while very few documents attempt at assessing possible animal-induced failure mechanisms. For latter, detection characterisation animal is crucial Electrical Resistivity Tomography (ERT) Ground Penetrating Radar are most employed geophysical techniques. Between 2017...
