Improvements to TITAN’s mass measurement and decay spectroscopy capabilities

March of the Titans: The Locomotor Capabilities of Sauropod Dinosaurs

Sauropod dinosaurs are the largest terrestrial vertebrate to have lived on Earth. This size must have posed special challenges for the musculoskeletal system. Scaling theory shows that body mass and hence the loads that must be overcome increases with body size more rapidly than either the ability of the muscles to generate force, or the ability of the skeleton to support these loads. Here we d...

Incidental Changes to Training Capabilities Due to Technological Improvements

During the development and enhancement of simulator systems, new technologies are incorporated to improve the training capabilities of the system. The degree to which changes to the simulator system improve training capabilities in anticipated areas is of primary interest; however, an evaluation of benefits from newly incorporated technologies should consider the impact on training capabilities...

Heavy Quark Spectroscopy and Decay

Pion mass and decay constant

Independent of assumptions about the form of the quark-antiquark scattering kernel we derive the explicit relation between the pion Bethe-Salpeter amplitude, Γπ, and the quark propagator in the chiral limit; Γπ necessarily involves a non-negligible γ5γ · P term (P is the pion four-momentum). We also obtain exact expressions for the pion decay constant, fπ, and mass, both of which depend on Γπ; ...

A precision measurement of the D s 1 ( 2536 ) + meson mass and decay width

The decay width and the mass of the Ds1(2536) ± have been measured via the decay channel D s1 → D K S using 232 fb −1 of data collected with the BABAR detector at the PEP-II asymmetricenergy ee storage ring. The result for the decay width is Γ(D s1) = (1.03 ± 0.05± 0.12)MeV/c , with the first error denoting the statistical uncertainty and the second one the systematic uncertainty. For the mass,...
