Omega+Omega ->(Omega Omega)(J)(pi)(=)o(+)+X cross section calculation

YW Yu, P Wang, ZY Zhang et al. · 2001

The cross sections of Omega+Omega --> (Omega Omega)(Jn=o+) +X are studied by using an effective Hamiltonian method. The results are sigma (Omega+Omega-->(Omega Omega )o+ +)gamma = 0 03 similar to 0.16 x 10(-29) cm(2) for p(Omega) = 100 similar to 400 MeV, and the cross sections of eta production are about 10(-28) cm(2) for p(Omega) > 880 MeV.

B Meson Decays to mega K*, omega rho, omega omega, omega phi, and omega f0

Aubert, B, Barate, R, Bóna, M et al. · CERN Bulletin · 2006

We describe searches for B meson decays to the charmless vector-vector final states omega K*, omega rho, omega omega, and omega phi with 233 times 10^{6} BB pairs produced in e+e- annihilation at sqrt{s}=10.58 GeV. We also search for the vector-scalar B decay to omega f_0. We measure the following branching fractions in units of 10^{-6}: BR(B0 --> omega K*0) = 2.4 +/- 1.1 +/- 0.7 (<4.2), BR(B+ --> omega K*+) = 0.6 {+1.4}_{-1.2} {+1.1}_{-0.9} (<3.4), BR(B0 --> omega rho0) = -0.6 +/- 0.7 {+0.8}_{-0.3} (<1.5), BR(B+ --> omega rho+) = 10.6 +/- 2.1 {+1.6}_{-1.0}, BR(B0 --> omega omega) = 1.8 {+1.3}_{-0.9} +/- 0.4 (<4.0), BR(B0 --> omega phi) = 0.1 +/- 0.5 +/- 0.1 (<1.2), and BR(B0 --> omega f_0) = 0.9 +/- 0.4 {+0.2}_{-0.1} (<1.5). In each case the first error quoted is statistical, the second systematic, and the upper limits are defined at the 90% confidence level. For B+ --> omega rho+ decays we also measure the longitudinal spin component f_L=0.82 +/- 0.11 +/- 0.02 and the charge asymmetry A_CP=0.04 +/- 0.18 +/- 0.02.

villekf/OMEGA: OMEGA v1.2.0

Wettenhovi, Ville-Veikko · Zenodo (CERN European Organization for Nuclear Research) · 2021

This is the official v.1.2.0 release of OMEGA. For changes since v1.1.1, see release notes. The biggest change in this release is the addition of (cone or fan beam) transmission tomography (e.g. CT imaging) support. A MATLAB toolbox package (OMEGA.-.Open-source.MATLAB.emission.tomography.software.mltbx) is recommended for anyone using MATLAB. It will automatically add the necessary folders to the path and you can easily uninstall the package from the Add-On Manager. Included are also precompiled mex-files for Linux (mexfiles_LINUX.7z) and Windows (mexfiles_WINDOWS.zip). However, you should use these ONLY if manual building fails.

The authors describe searches for B meson decays to the charmless vector-vector final states {omega}K*, {omega}p, {omega}{omega}, and {omega}{phi} with 233 x 10{sup 6} B{bar B} pairs produced in e{sup +}e{sup -} annihilation at {radical}s = 10.58 GeV. They also search for the vector-scalar B decay to {omega}f{sub 0}.

Pseudoscalar production at omega omega threshold in J/psi -> gamma omega omega

Bes Collaboration · arXiv (Cornell University) · 2006

The decay channel J/ψ->gamma omega omega, omega -> pi+ pi- pi0 is analyzed using a sample of 5.8x10^7 J/psi events collected with the BESII detector. The omega omega invariant mass distribution peaks at 1.76 GeV/c^2, just above the omega omega threshold. Analysis of angular correlations indicate that the omega omega system below 2 GeV/c^2 is predominantly pseudoscalar. A partial wave analysis confirms the predominant pseudoscalar structure, together with small 0^{++} and 2^{++} contributions, and yields a pseudoscalar mass M = 1744 \pm 10 (stat) \pm 15 (syst) MeV/c^2, a width Gamma = 244^{+24}_{-21} (stat) \pm 25 (syst) MeV/c^2, and a product branching fraction Br(J/psi-> gamma eta(1760)) \cdot Br(η(1760)->omega omega) = (1.98 \pm 0.08 (stat) \pm 0.32 (syst)) x 10^{-3}.

Omega (??) and Inverted Omega Incision

Zlatko Vlajčić, Rado Žic, Sanda Stanec et al. · Annals of Plastic Surgery · 2004

In the history of breast surgery, we have seen a lot of changes in orientation, position, and localization of breast incisions. Most of the biopsy incisions have been made with no consideration of future mastectomy or reconstruction because a wide ellipse of skin removed during the mastectomy included the biopsy site. The primary surgical treatment was in the competence of the oncologic or general surgeon. Reconstruction was not an integral part of breast carcinoma therapy and was considered as a secondary, unimportant treatment to be preformed by a plastic surgeon at a later date if desired by the patient. Wide acceptance of conservative breast operations, skin-sparing mastectomy, and reconstruction as an integral part of breast cancer therapy necessitates new consideration about the initial incisions used for breast biopsy. We consider the omega incision not only as a type of incision but also as a concept that can be used for all breast surgery, including biopsy, lumpectomy, skin-sparing mastectomy, and reconstruction.
