Particle-particle correlations: Femtoscopy and tools for spectroscopy

Non-Identical Particle Femtoscopy in Models with Single Freeze-Out

We present femtoscopic results from hydrodynamics-inspired thermal models with single freeze-out. Nonidentical particle femtoscopy is studied and compared to results of identical particle correlations. Special emphasis is put on shifts between average space-time emission points of non-identical particles of different masses. They are found to be sensitive to both the spatial shift coming from r...

Three-Particle Azimuthal Correlations

Two-particle azimuthal correlations in central Au+Au collisional at RHIC have revealed a broadened away-side structure, with respect to perpherial Au+Au, pp, and d+Au. This could be explained by different physics mechanisms such as: large angle gluon radiation, deflected jets, Ĉerenkov gluon radiation, and conical flow generated by hydrodynamic shock-waves. We can discriminate the scenarios wit...

Negative Correlations and Particle Systems

Aerosol particle molecular spectroscopy.

The molecular spectroscopy of a solution particle by structure resonance modulation spectroscopy is discussed [S. Arnold and A. B. Pluchino, "Infrared Spectrum of a Single Aerosol Particle by Photothermal Modulation of Structure Resonances," Appl. Opt. 21, 4194 (1982); S. Arnold et al., "Molecular Spectroscopy of a Single Aerosol Particle," Opt. Lett. 9, 4 (1984)]. Analytical equations are deri...

Competition Between Particle - Hole and Particle - Particle Correlations in Forbidden Electron Capture : the Case of 123

The K-electron capture half-life of 123 Te has been recently measured to be t K exp = 2.4 × 10 19 yr, and constitutes the longest half-life ever measured in a single β-transition of any nuclear species. We have calculated this second unique forbidden transition within the framework of the proton-neutron quasi-particle random phase approximation, making use of Skyrme-type effective interactions....
