Down Type Isosinglet Quarks in ATLAS

R. Mehdiyev, A. Siodmok, S. Sultansoy +1

We evaluate the discovery reach of the ATLAS experiment for down type isosinglet quarks, , using both their neutral and charged decay channels, namely the process $pp\to D\bar{D…

Study of Polarization in B -> VT Decays

Alakabha Datta, Yanyan Gao, Andrei V. Gritsan +3

In this paper, we examine B -> VT decays (V is a vector and T is a tensor meson), whose final-state particles can have transverse or longitudinal polarization. Measurements have be…

Field theoretic description of the abelian and non-abelian Josephson effect

F. Paul Esposito, L. -P. Guay, R. B. MacKenzie +2

We formulate the Josephson effect in a field theoretic language which affords a straightforward generalization to the non-abelian case. Our formalism interprets Josephson tunneling…

Testing Explanations of the Polarization Puzzle

Alakabha Datta, Andrei V. Gritsan, David London +2

($\btos$) is three separate decays, one for each polarization of the final-state vector mesons (one longitudinal, two transverse). It is observed that the fraction of tr…

Is There Still a B -> pi K Puzzle?

Seungwon Baek, David London

We perform a fit to the 2006 B -> pi K data and show that there is a disagreement with the standard model. That is, the B -> pi K puzzle is still present. In fact, it has gotten wo…

U-Spin Tests of the Standard Model and New Physics

Makiko Nagashima, Alejandro Szynkman, David London

Within the standard model, a relation involving branching ratios and direct CP asymmetries holds for the B-decay pairs that are related by U-spin. The violation of this relation in…

CP Violation in Supersymmetric Theories: stop2->stop1 H H, stop2->stop1 Z Z, stop2->stop1 W+ W-, stop2->stop1 Z H

Alejandro Szynkman, Ken Kiers, David London

We study the decays stop2->stop1 H H, stop2->stop1 Z Z, stop2->stop1 W+ W- and stop2->stop1 Z H, with an eye towards measuring the CP-violating supersymmetric parameters contained…
