New physics searches using top quarks

This review summarizes recent searches for new physics at the Fermilab Tevatron Collider using final states involving top quarks and their analogues. The DØ and CDF Collaborations have used samples as large as 5 fb−1 to search for charged Higgs bosons, massive resonances decaying to t ¯t pairs, massive vector bosons decaying to t¯b final states, fourth-generation t' quarks and supersymmetric stop (˜t) quarks. These analyses have resulted in some of the most sensitive searches for new phenomena in the 1.96TeV ¯pp collisions

Coupled hygrothermal, electrochemical, and mechanical modelling for deterioration prediction in reinforced cementitious materials

In this paper a coupled hygrothermal, electrochemical, and mechanical modelling approach for the deterioration prediction in cementitious materials is briefly outlined. Deterioration prediction is thereby based on coupled modelling of (i) chemical processes including among others transport of heat and matter as well as phase assemblage on the nano and micro scale, (ii) corrosion of steel including electrochemical processes at the reinforcement surface, and (iii) material performance including corrosion- and load-induced damages on the meso and macro scale. The individual FEM models are fully coupled, i.e. information, such as such as corrosion current density, damage state of concrete cover, etc., are constantly exchanged between the models
