Resonance phenomena at high level density

High pT Phenomena at RHIC

First data from RHIC reveals a suppression of hadron production at high pT in central Au-Au collisions relative to the expectation from nucleonnucleon collisions. Known nuclear effects are excluded as origin. The apparent suppression of high pT hadrons thus indicates quenching of jet production. The origin of this jet quenching is uncertain and whether it is related to parton energy loss throug...

Determination of the nuclear level density at high excitation energy.

Evaporation simulations are presented to illustrate the problems associated with the determination of the nuclear level density constant at high excitation energy from evaporation spectra. The methods of using either the total (whole chain) spectra or the difference (from two different initial excitation energies) spectra are discussed. Data from the study of the reaction 701 MeV 'Si+ ' Mo are ...

High-Density Lipoprotein Measurement Methods: From Precipitation to Nuclear Magnetic Resonance (NMR)

Introduction: Extensive research suggests a common hypothesis regarding the protective role of total high-density lipoprotein-cholesterol (HDL-C) against cardiovascular disease (CVD). This hypothesis indicates an inverse relationship between CVD and high HDL-C levels. Various mechanisms, such as reverse cholesterol transport, besides anti-inflammatory and antioxidant functions, indicate HDL-C a...

Qualitons At High Density

In the color-flavor-locked (CFL) phase of the QCD superconductor we show that baryons behave as qualitons (called “superqualitons”) with quantum numbers B = (1 mod 2)/3, S = 1/2 and Y = B. Bound superqualitons may cause the superconducting gap in the CFL phase to be effectively nonexistent, a novel phenomenon not seen in conventional superconductors.
