841“…To help in reading the chapters without having to constantly consult other texts, essential materials from General Relativity and the theory of elementary particles are collected in the appendices. Various hypotheses dealing with unsolved problems of cosmology, and often alternative to each other, are discussed at a more advanced level. …”

Fifty years later, there have been five hadron colliders in the world, three at CERN and two in the US, each of which has enriched the sum of human knowledge and contributed to innovation in numerous ways. …”

845por Veronesi, Michele“…Since boson and fermion fields enter virtually in $B^0_s-\overline{B}^0_s$ transitions, the measurement of the $B^0_s$ oscillation frequency does not only offer a laboratory to study the beautiful quantum mechanical properties of the subatomic world, but also provides a gateway to the relativistic quantum fields constituting all elementary particles and fundamental interactions. …”

847“…Tests for deviation from the Standard Model (SM) are guided by its apparent incompleteness and by pursuit of creation of a more general theory of elementary particles. We search in this study for manifestations of new physics in an indirect way, through changes in interactions of already known particles due to the effects of physics beyond the SM. …”

This very massive structure is expected to lay on the floor in a possible future underground facility at CERN, where the seismic activity is non-negligible. …”

The typical cold mass of a detector magnet ranges from 1 to 40 tons, and typical cryoplant cooling capacities are between 400 and 800 W/4.5 K entropy equivalent. …”

852“…The precise measurement of the top quark mass is one of the main physics goals in understanding the interactions between the elementary particles. The Large Hadron Collider will collect an enormous amount of pp->ttbar events, which will in the semi-leptonic decay mode ttbar->bWbW->bqqblv (l=muon) allow to measure the top quark mass to an unprecedented precision dominated by systematic uncertainties in the jet definition. …”
