Von Neumann Algebra Automorphisms and Time-Thermodynamics Relation in General Covariant Quantum Theories
A. Connes, C. Rovelli
We consider the cluster of problems raised by the relation between the notion of time, gravitational theory, quantum theory and thermodynamics; in particular, we address the proble…
Radiation hardness qualification of PbWO4 scintillation crystals for the CMS Electromagnetic Calorimeter
The CMS Electromagnetic Calorimeter Group, P. Adzic, N. Almeida +267
Ensuring the radiation hardness of PbWO4 crystals was one of the main priorities during the construction of the electromagnetic calorimeter of the CMS experiment at CERN. The produ…
Spacetime Lagrangian Formulation of Barbero-Immirzi Gravity
L. Fatibene, M. Francaviglia, C. Rovelli
We shall here discuss a new spacetime gauge-covariant Lagrangian formulation of General Relativity by means of the Barbero-Immirzi SU(2)-connection on spacetime. To the best of our…
Response of microchannel plates in ionization mode to single particles and electromagnetic showers
A. Yu. Barnyakov, M. Yu. Barnyakov, L. Brianza +22
Hundreds of concurrent collisions per bunch crossing are expected at future hadron colliders. Precision timing calorimetry has been advocated as a way to mitigate the pileup effect…
Response of microchannel plates to single particles and to electromagnetic showers
L. Brianza, F. Cavallari, D. Del Re +22
We report on the response of microchannel plates (MCPs) to single relativistic particles and to electromagnetic showers. Particle detection by means of secondary emission of electr…
Casimir energy for two and three superconducting coupled cavities
L. Rosa, S. Avino, E. Calloni +16
In this paper we study the behavior of the Casimir energy of a "multi-cavity" across the transition from the metallic to the superconducting phase of the constituting plates. Our a…
