• (American Physical Society, 1995)
We investigate the issue of testing $CPT$ invariance in the neutral-$D$ system, using $D$ events obtained either from fixed-target experiments or from a $\tau$-charm factory. For both types of experiments we show that the ...
• (American Physical Society, 1997)
A theoretical framework is introduced that describes possible $CPT$-violating effects in the context of quantum electrodynamics. Experiments comparing the anomalous magnetic moments of the electron and the positron can ...
• (American Physical Society, 2014)
The recent observation of high-energy astrophysical neutrinos can be used to constrain violations of Lorentz invariance emerging from a quantum theory of gravity. We perform threshold and Čerenkov analyses that improve ...
• (Physics Letters B, 1995)
The issue of testing $\text{CPT}$ invariance at a $\text{B}$ factory is considered. We present asymmetries that permit a clean extraction of quantities parametrizing direct and indirect $\text{CPT}$ violation, using ...
• (Nuclear Physics B, )
We define the string space-time symmetries $\text{C,P,T}$ and their products. The effects of nonlocal interactions and the infinite number of particle fields are incorporated using string field theory. At the dynamical ...
• (Physics Letters B, 1997)
We examine the effects on baryogenesis of spontaneous $\text{CPT}$ violation in a string-based scenario. Under suitable circumstances, certain $\text{CPT}$-violating terms can produce a large baryon asymmetry at the ...

• (Physics Letters B, 2011)
A three-parameter model of neutrino oscillations based on a simple Lorentz- and $\text{CPT}$-violating texture is presented. The model is consistent with established data and naturally generates low-energy and neutrino–a ...
• (American Physical Society, 2012)
I study the effects of particle-hole imbalance on the exciton superfluid formed in a topological insulator thin film and obtain the mean-field phase diagram. At finite imbalance a spatially modulated condensate is formed, ...
• (American Physical Society, 1989)
Superstrings with critical dimension two and two real bosonic spacetime coordinates may serve as useful toy models for the study of string properties. We present details of several such toy superstrings including open, ...
• (American Physical Society, 2012)
Earlier work has shown that a narrow-frequency-band, wide-angle emission is produced by an array of metal patches supported on a thin dielectric layer covering a ground plane. The modes responsible for this emission are ...
• (American Physical Society, 2012)
Based on a data sample of $106×10^6$ $\psi '$ events collected with the BESIII detector, the decays $\psi '\rightarrow\gamma\chi_{c0,2}, \chi_{c0,2}\rightarrow\gamma\gamma$ are studied to determine the two-photon widths ...
• (American Physical Society, 2003)
The amplitude for vacuum photon splitting was studied in the context of the general Lorentz- and CPT-violating quantum electrodynamics (QED) extension. At leading order in certain coefficients for Lorentz violation, a ...
• (American Physical Society, 2012)
We investigate interaction-induced valley domain walls in bilayer graphene in the $\nu = 0$ quantum Hall state, subject to a perpendicular electric field that is antisymmetric across a line in the sample. Such a state can ...
• (American Physical Society, 2012)
We use distorted wave electron scattering calculations to extract the weak charge form factor $F_W(\bar{q})$, the weak charge radius $R_W$, and the point neutron radius $R_n$ of $^{208}\text{Pb}$ from the Lead Radius ...
• (American Physical Society, 2012)
We present a fit to precision electroweak data in the standard model (SM) extended by an additional vector boson, $Z′$, with suppressed couplings to the electron compared to the $Z$ boson, with couplings to the b-quark, ...
• (American Physical Society, 2012)
We present a measurement of $p\bar{p}\rightarrow Z\gamma\rightarrow\ell^+\ell^-\gamma (\ell = e, \mu)$ production with a data sample corresponding to an integrated luminosity of $6.2$ $\text{fb}^{-1}$ collected by the D0 ...
