Análisis del comercio electrónico

El trabajo busca analizar el comercio electrónico en todo su conjunto, partiendo desde su evolución histórica hasta llegar a la actualidad, pasando por los tipos de comercio electrónico que existe y los métodos de pago online. También se analizará una empresa significativa del sector como es Amazon para poder comprender mejor el sector. Una vez hecho esto se realizará un análisis DAFO del comercio electrónico.Grado en Comerci

Search for Scalar Diphoton Resonances in the Mass Range 65−60065-600 GeV with the ATLAS Detector in pppp Collision Data at s\sqrt{s} = 8 TeVTeV

A search for scalar particles decaying via narrow resonances into two photons in the mass range 65–600 GeV is performed using $20.3\text{}\text{}{\mathrm{fb}}^{-1}$ of $\sqrt{s}=8\text{}\text{}\mathrm{TeV}$ $pp$ collision data collected with the ATLAS detector at the Large Hadron Collider. The recently discovered Higgs boson is treated as a background. No significant evidence for an additional signal is observed. The results are presented as limits at the 95% confidence level on the production cross section of a scalar boson times branching ratio into two photons, in a fiducial volume where the reconstruction efficiency is approximately independent of the event topology. The upper limits set extend over a considerably wider mass range than previous searches
