Traces and Quasi-traces in Operator Algebras

School
MATHEMATICS

We discuss the central role of (quasi-traces in the study of operator algebras. We review some of the earlier applications as well as new interests due to the classification program. This review is based on a personal selection of topics and is neither comprehensive nor technical. ...

Generalized continua for mechanics at different scales

Generalized continuum mechanics successes in capturing features that cannot be addressed in a classical continuum theory. Generalized continua has been extensively applied for the analysis of various structures (such as beams, plates, and shells) at arbitrary scales from macro to nano. Considering the phenomenon and material/structure, appropriate generalization should be employed. Classical continuum mechanics predicts singular (stress, strain ...) fields at dislocation cores or crack tips. These singular fields of defects have been taken care of carefully in the class ...

Model-independent constraints on the CKM matrix elements |V_{tb}|, |V_{ts}| and |V_{td}|

School
PARTICLES AND ACCELERATORS

Single top quark production cross sections at hadron colliders are traditionally used to extract the modulus of the V_{tb} element of the Cabibbo-Kobayashi-Maskawa matrix under the following assumption: |V_{tb}| >> |V_{td}|, |V_{ts}|. We show that direct limits on |V_{td}| and |V_{ts}| can be extracted from differential measurements of single top quark cross sections in t-channel as a function of the rapidity of the light jet recoiling against the top quark, its angular distance from the reconstructed top quark, and the rapidity of the b quark from top quark decay. We perform a global fit of top quark related CKM elements to experimental da ...
