Imaging spectrum of mesenteric masses

Abdominal Radiology, 2020
Mesenteries are extensions of the visceral and parietal peritoneum consisting of fat, vessels, nerves, and lymphatics. Mesenteric masses have a wide differential diagnosis with neoplastic, infectious, or inflammatory etiologies and can either be solid or cystic. Imaging features are critical for the diagnosis.

Baryon Mass Spectrum

Physical Review, 1960
It is assumed that the $\ensuremath{\pi}$-baryon interactions are universal and the $K$-baryon interactions account for the large mass differences between baryons. If further all baryon spins are \textonehalf{} and $K$ spin is zero, ($\ensuremath{\Sigma}, \ensuremath{\Lambda}$) parity is even, the ($\ensuremath{\Sigma}, \ensuremath{\Lambda}$) mass ...

Charmonium: the mass spectrum

Canadian Journal of Physics, 1981
The charmonium mass spectrum is evaluated using the oscillator potential as responsible for long range confinement. Hyperfine splittings for the color singlet [Formula: see text] system are discussed using various approaches. The mass of [Formula: see text] and [Formula: see text] are also briefly touched upon.
