• (American Physical Society, 2012)
We calculate the leptonic decay constants of $B_{(s)}$ and $D_{(s)}$ mesons in lattice QCD using staggered light quarks and Fermilab bottom and charm quarks. We compute the heavy-light-meson correlation functions on the ...
• (American Physical Society, 2012)
We calculate form-factor ratios between the semileptonic decays $\overline{B}^{0} \rightarrow D^{+}\ell^{-}\overline{\nu}$ and $\overline{B}^{0}_{s} \rightarrow D^{+}_{s}\ell^{-}\overline{\nu}$ with lattice QCD. These ...
• (Physics Letters B, 2001)
Photoproduction of neutral-kaon pairs is studied from the perspective of $\text{CP}$ and $\text{CPT}$ studies. Interference of the $\text{P}$- and $\text{S}$-waves, with the former due to diffractive $\phi$ production and ...
• (Frontiers Media S.A., 2012)
Relatively recent work has reported that networks of neurons can produce avalanches of activity whose sizes follow a power law distribution. This suggests that these networks may be operating near a critical point, poised ...
• (Elsevier, 2012)
Bipartite Riemann–Finsler geometries with complementary Finsler structures are constructed. Calculable examples are presented based on a bilinear-form coefficient for explicit Lorentz violation.
• (American Physical Society, 2004)
A search for an annual variation of a daily sidereal modulation of the frequency difference between colocated $^{129}\text{Xe}$ and $^{3}\text{He}$ Zeeman masers sets a stringent limit on boost-dependent Lorentz and $CPT$ ...
• (American Physical Society, 1996)
The feasibility of placing bounds on $CPT$ violation from experiments with neutral $B$ mesons is examined. We consider situations with uncorrelated mesons and ones with either unboosted or boosted correlated mesons. ...
• (American Physical Society, 2012)
Core-collapse supernovae may depend sensitively on charged-current neutrino interactions in warm, low-density, neutron-rich matter. A proton in neutron-rich matter is more tightly bound than is a neutron. This energy shift ...
• (American Physical Society, 2012)
We present results on the chiral and deconfinement properties of the QCD transition at finite temperature. Calculations are performed with 2+1 flavors of quarks using the p4, asqtad, and HISQ/tree actions. Lattices with ...
• (Elsevier, 2010)
Classical point-particle relativistic lagrangians are constructed that generate the momentum–velocity and dispersion relations for quantum wave packets in Lorentz-violating effective field theory.
• (American Physical Society, 2002)
Clock-comparision experiments on satellite and other spacecarft were used to determine unmeasured coefficients for Lorentz and CPT violation. The presence of Lorentz and CPT violation caused frequency shifts in certain ...
• (American Physical Society, 2012)
We derive an effective field-theoretical model for the one-dimensional collective mode associated with a domain wall in a quantum Hall ferromagnetic state, as realized in confined graphene systems at zero filling. To this ...
• (American Physical Society, 1990)
A second-quantized analysis is performed to examine many-body phenomena in closed bosonic strings. The covariant nonpolynomial closed-string field theory is developed in terms of particle fields and shown to contain ...
• (American Physical Society, 2012)
We report the combination of recent measurements of the helicity of the W boson from top quark decay by the CDF and D0 collaborations, based on data samples corresponding to integrated luminosities of $2.7-5.4\text{ ... • (American Physical Society, 2012) We present the results of the combination of searches for the standard model Higgs boson produced in association with a$W$or$Z$boson and decaying into$b\bar{b}\$ using the data sample collected with the D0 detector in ...
• (American Association of Physics Teachers, 2012)
We survey various numerical methods for finding solutions of quantum confined states. We especially consider states in two-dimensional (2D) tubes, or 2D surfaces that are confined in the transverse direction but are ...
• (American Physical Society, 1999)
Constraints from clock-comparison experiments on violations of Lorentz and CPT symmetry are investigated in the context of a general Lorentz-violating extension of the standard model. The experimental signals are shown to ...
• (Physics Letters B, 2015)
Limits on gravitational Čerenkov radiation by cosmic rays are obtained and used to constrain coefficients for Lorentz violation in the gravity sector associated with operators of even mass dimensions, including ...
• (American Physical Society, 2013)
Tiny violations of the Lorentz symmetry of relativity and the associated discrete CPT symmetry could emerge in a consistent theory of quantum gravity such as string theory. Recent evidence for linear polarization in gamma-ray ...
• (American Physical Society, 2012)
The symmetry energy contribution to the nuclear equation of state impacts various phenomena in nuclear astrophysics, nuclear structure, and nuclear reactions. Its determination is a key objective of contemporary nuclear ...
