c](3900) could be a single entity of four quarks, Skwarnicki says, but it could also be a coupling of two mesons, analogous to two atoms linking up to form a molecule.
Figure 3 shows that maximum of mesons occupy the spectral node S = [8] that split up the interval of S = [0] to S = [12] between the electron and the Wand Z-bosons proportionally of 2/3.
In conclusion, Golconda emphasized that they believe calling a special meeting is in the best interest of stockholders to ensure that they are able to act on the proposals to be brought by Meson in a timely manner, including the election of Meson Capital's director candidates.
LHCb has already been intimately involved in refining those prior measurements; in March 2012, the team confirmed earlier oscillation observations of a meson called Bs, and published the result in Physics Letters B.
We will abstain from further calculations here and for the moment consider it sufficient to have shown a double electron-mass in the meson, pointing to the self-gravitation also of the virtual mass as a probable solution to the deficiency of ~4.
At the same time the strong repulsion of two nucleons at short distances, understood qualitatively in terms of the Fermi statistics of the quarks in the nucleons and the high energy cost of flipping a quark spin in the nucleon, means that the dynamical mechanism for the weak interaction between nucleons must involve meson exchange and the soft QCD physics that leads to it.
Particles called B, mesons seemed to be disintegrating into a muon (a cousin of the electron) and an anti-muon more frequently than expected.
Tucked away on the corner of Wood Street, just off John William Street, down the side of the Cherry Tree Wetherspoons pub, is Meson La Pepa, a superb little Spanish restaurant which was previously the Italian Mona Lisa's and is situated opposite Caribbean specialists Discovery Bay.
Theoretical descriptions of the weak nucleon-nucleon interaction are traditionally based on an effective meson exchange model in which the coupling constants for parity violating [pi], [rho], and [omega] meson exchanges set the scale for weak interaction effects and are uncertain to within factors of 2 to 3 on theoretical grounds [1].
We were ready for some of the Yucatan's cuisine, and our trusty guidebook, Cadogan's ``Yucatan and Mayan Mexico,'' recommended El Meson de Marques, a historic whitewashed hotel overlooking the park.
Using electron and positron beams, the B Factory is designed to probe the decay of the B Meson particle to determine differences in the behavior of matter and antimatter.
It refers to a particle called the B-bar meson that decays into a D meson, an anti-neutrino and a tau lepton (3B to D-star-tau-nu2).
