0 n - p Short - Range Correlations from ( p , 2 p + n ) Measurements

چکیده
Recently, a new technique for measuring short-range NN correlations in nuclei (NN SRCs) was reported by the E850 collaboration, using data from the EVA spectrometer at the AGS at Brookhaven Nat. Lab. In this talk, we will report on a larger set of data from new measurement by the collaboration, utilizing the same technique. This technique is based on a very simple kinematic approach. For quasielastic knockout of protons from a nucleus (C(p,2p) was used for the current work), we can reconstruct the momentum pf of the struck proton in the nucleus before the reaction, from the three momenta of the two detected protons, p1 and p2 and the three momentum of the incident proton, p0 :

Short - range nucleon correlations and neutrino emission by neutron stars at low temperatures
We argue that the strong interaction between protons and neutrons in the asymmetric liquid (neutron star) distorts strongly proton Fermi surface. We use the Feynman diagram approach to calculate probability of triple (e-p-n) short range correlations in terms of the short range (p-n) correlations and ultrarelativistic Coulomb (p-e) interaction. We find that these correlations lead to holes in (e...

New measurements of short-range and long-range two-particle correlations, azimuthal anisotropy, and event-by-event fluctuations from the STAR experiment for √ s N N = 130 and 200 GeV Au+Au collisions are summarized. Striking evidence is presented for large, non-statistical fluctuations in mean transverse momentum. Descriptions of the data in terms of phenomenological source function models are ...

The two-body momentum distribution η 2 (p 1 , p 2) of nuclei is studied. First, a compact analytical expression is derived for Z = N , ℓ-closed nuclei, within the context of the independent particle shell model. Application to the light closed-shell nucleus 16 O is included and discussed. Next, the effect of dynamical, short-range correlations is investigated in the case of the light nucleus 4 ...
متن کاملComparison between the Short Term and Durability Effects of Proprioceptive Neuromuscular Facilitation Exercise and Instrument Assisted soft Tissue Mobilization Technique on Ankle-Dorsiflexion Range of Motion
Introduction: Reduced lower extremity range of motion and movement leads to a decrease in movement efficiency; accordingly, it is vital to maintain the range of motion to prevent damage and improve functions. The purpose of this study was to compare the short term and durability effects of Instrument Assisted Soft Tissue Mobilization (IASTM) and Proprioceptive Neuromuscular Facilitation (PNF) t...

The Unitary Correlation Operator Method (UCOM) provides a means for nuclear structure calculations starting from realistic NN potentials. The dominant short-range central and tensor correlations are described explicitly by a unitary transformation. The application of UCOM in the context of the no-core shell model provides insight into the interplay between dominant short-range and residual long...
