We consider pure glue QCD at beta=5.7, beta=6.0 and beta=6.3. We evaluate the gluon propagator both in time at zero 3-momentum and in momentum space. From the former quantity we obtain evidence for a...
Probing CP Violation Via Higgs Decays to Four Leptons (1993)
Since decays to four leptons is widely considered a promising way to search for the Higgs particle, we show how the same final state can also be used to search for signals of CP nonconservation....
The Gluon Propagator in Momentum Space (1992)
Bernard, C., Parrinello, C., Soni, A.
We give preliminary numerical results for the gluon propagator evaluated both in coordinate and momentum space on a 16^3X40 quenched lattice at beta=6.0. Our findings are compared with earlier...
A General Lower Bound for Radiative B Decay (1992)
Atwood, David, Burgess, C. P., Soni, A.
In a wide class of models -- including the standard model -- flavor-changing neutral currents are suppressed by an approximate chiral symmetry of the low-energy lagrangian. This symmetry allows the...
Hou, Wei-Shu, Soni, A., Steger, Herbert
The effects of a fourth family on the decays b-->s(d)[gamma] are reported. The BR(b-->s[gamma]) can become ~10-3, i.e., a gain from the three-generation result by an order of magnitude. For...
Application of chiral perturbation theory to K→2π decays (1985)
Bernard, Claude, Draper, Terrence, Soni, A., Politzer, H. David, Wise, Mark B.
Chiral perturbation theory is applied to the decay K→2π. It is shown that, to quadratic order in meson masses, the amplitude for K→2π can be written in terms of the unphysical amplitudes K→π...
Fidelity of two retroviral reverse transcriptases during DNA-dependent DNA synthesis in vitro.
Roberts, J D, Preston, B D, Johnston, L A, Soni, A, Loeb, L A, Kunkel, T A
We determined the fidelity of avian myeloblastosis virus and Moloney murine leukemia virus reverse transcriptases (RTs) during DNA synthesis in vitro using the M13mp2 lacZ alpha gene as a mutational...

Renal ultrastructural markers in AIDS-associated nephropathy.
Chander, P., Soni, A., Suri, A., Bhagwat, R., Yoo, J., Treser, G.
Renal tissues from two groups of patients with acquired immune deficiency syndrome (AIDS) were examined: Group A had severe proteinuria and varying degrees of renal insufficiency, designated...
