Calculated corrections to superallowed Fermi beta decay: New evaluation of the nuclear-structure-dependent terms
(American Physical Society, 2002)
The measured ft values for superallowed 0(+)-->0(+) nuclear beta decay can be used to obtain the value of the vector coupling constant and thus to test the unitarity of the Cabibbo-Kobayashi-Maskawa matrix. An essential ...
Giant monopole strength in Ni-58
(American Physical Society, 2000)
The strength distribution of the giant monopole resonance in Ni-58 has been measured from E-x = 10 to 35 MeV using small-angle scattering of 240-MeV alpha particles. E0 strength corresponding to 74(-12)(+22)% of the E0 ...
Systematic measurements of identified particle spectra in pp, d plus Au, and Au plus Au collisions at the STAR detector
(American Physical Society, 2009)
Identified charged-particle spectra of pi(+/-), K(+/-), p, and (p) over bar at midrapidity (vertical bar y vertical bar < 0.1) measured by the dE/dx method in the STAR (solenoidal tracker at the BNL Relativistic Heavy Ion ...
Multiplicity and pseudorapidity distributions of charged particles and photons at forward pseudorapidity in Au plus Au collisons at root s(NN)=62.4 GeV
(American Physical Society, 2006)
We present the centrality-dependent measurement of multiplicity and pseudorapidity distributions of charged particles and photons in Au+Au collisions at root s(NN)=62.4 GeV. The charged particles and photons are measured ...
Pion production by protons on a thin berylLium target at 6.4, 12.3, and 17.5 GeV/c incident proton momenta
(American Physical Society, 2008)
An analysis of inclusive pion production in proton-berylLium collisions at 6.4, 12.3, and 17.5 GeV/c proton beam momentum has been performed. The data were taken by Experiment 910 at the Alternating Gradient Synchrotron ...
Cross section for charmonium absorption by nucleons
(American Physical Society, 2002)
The cross section for J/psi absorption by nucleons is studied using a gauged SU(4) hadronic Lagrangian but with empirical particle masses, which has been used previously to study the cross sections for J/psi absorption by ...
Jet conversions in a quark-gluon plasma
(American Physical Society, 2007)
Quark and gluon jets traversing through a quark-gluon plasma not only lose their energies but also can undergo flavor conversions. The conversion rates via the elastic q((q) over bar )g -> gq((q) over bar )and the inelastic ...
Strangelet search in Au plus Au collisions at root s(NN)=200 GeV
(American Physical Society, 2007)
We have searched for strangelets in a triggered sample of 61 million central (top 4%) Au+Au collisions at root s(NN)=200 GeV near beam rapidities at the STAR solenoidal tracker detector at the BNL Relativistic Heavy Ion ...
Asymptotic normalization coefficients and the Be-7(p, gamma)B-8 astrophysical S factor
(American Physical Society, 2001)
We consider the results of two proton transfer reactions, B-10(Be-7, B-8)Be-9 and N-14(Be-7, B-8)C-13, to obtain a weighted average of the measured asymptotic normalization coefficients for the virtual transition 7Be +pB-8. ...
J/Psi suppression in ultrarelativistic nuclear collisions
(American Physical Society, 2000)
Using a multiphase transport model, we study the relative importance of J/psi suppression mechanisms due to plasma screening, gluon scattering, and hadron absorption in heavy ion collisions at the Relativistic Heavy Ion ...
