What if the Mass Difference is around 18 Inverse Picoseconds?

A. Ali, D. London

Present experiments in pursuit of the mass difference in the Bs-Bs(bar) system have put a lower bound on this quantity of (at 95% C.L.). The same experiments…

Searching for New Physics via CP Violation in B -> pi pi

D. London, N. Sinha, R. Sinha

It is well known that one can use B -> pi pi decays to probe the CP-violating phase α. In this paper we show that these same decays can be used to search for new physics. This is d…

Supersymmetric Large Extra Dimensions Are Small and/or Numerous

D. Atwood, C. P. Burgess, E. Filotas +3

Recently, a scenario has been proposed in which the gravitational scale could be as low as the TeV scale, and extra dimensions could be large and detectable at the electroweak scal…

Supersymmetric Effects on Isospin Symmetry Breaking and Direct CP Violation in

A. Ali, L. T. Handoko, D. London

We argue that one can search for physics beyond the standard model through measurements of the isospin-violating quantity , its…

Extracting Weak Phase Information from B -> V_1 V_2 Decays

David London, Nita Sinha, Rahul Sinha

We describe a new method for extracting weak, CP-violating phase information, with no hadronic uncertainties, from an angular analysis of B -> V_1 V_2 decays, where V_1 and V_2 are…

T-Odd Triple-Product Correlations in Hadronic b Decays

W. Bensalem, D. London

We study T-violating triple-product asymmetries in the quark-level decay b -> s u u(bar) within the standard model (SM). We find that only two types of triple products are non-negl…

Discrete Ambiguities in B-Decay CP Asymmetries and the Search for New Physics

David London

The first measurements of CP violation in the B system will probably extract , and . Assuming that the CP angles , and are the interior angle…

rho_T Production via W_L Z_L Fusion at Hadronic Colliders

S. Slabospitsky, G. Azuelos

Multiscale technicolor models predict the existence of high mass resonances at hadron colliders. Although the quark fusion process of production dominates, vector boson fusion offe…

CP Violation and Quark Mixing

Ahmed Ali, David London

Measurements of CP asymmetries in B decays will soon be made at factories and hadron machines. In light of this, we review and update the profile of the CKM unitarity triangle…

Is it possible to Measure the Weak Phase of a Penguin Diagram?

D. London, N. Sinha, R. Sinha

The penguin amplitude receives contributions from internal , and -quarks. We show that it is impossible to measure the weak phase of any of these penguin contrib…
