Erratum; Impact of tensor force on $$beta$$ decay of magic and semimagic nuclei [Phys. Rev. Lett. 110, 122501 (2013)]

In the paper [F.Minato and C.L. Bai, Phys. Rev. Lett. 110, 122501], errors were found in the calculation of the Fermi function and the residual interaction of the spin-orbit part in RPA. The former estimates the final state interaction between outgoing electron and daughter nucleus resulted from beta-decay, and the latter contributes to A and B submatrices in the RPA. The errors have been corrected and it was found that the result didn't change significantly.

Impact of tensor force on $$beta$$-decay of magic and semimagic nuclei

Effect of the tensor force on $$beta$$-decay is studied in the framework of the proton-neutron random-phase-approximation (RPA) with the Skyrme force. The investigation is performed for even-even sub-magic and magic nuclei, $$^{42}$$Si, $$^{68,78}$$Ni and $$^{132}$$Sn. The tensor correlation induces strong impact on low-lying Gamow-Teller state and its collectivity. In particular, it improves the $$beta$$-decay half-lives. $$Q$$ and $$ft$$ values are also investigated and compared with experimental data.

Transverse momentum distributions and yields for $$pi^{pm}, K^{pm}, p$$, and $$bar{p}$$ in $$p + p$$ collisions at $$sqrt{s}$$ = 200 and 62.4 GeV at midrapidity are measured by the PHENIX experiment at the RHIC. We present the inverse slope parameter, mean transverse momentum, and yield per unit rapidity at each energy, and compare them to other measurements at different $$sqrt{s}$$ collisions. We also present the scaling properties such as $$m_T$$ and $$x_T$$ scaling and discuss the mechanism of the particle production in $$p + p$$ collisions. The measured spectra are compared to next-to-leading order perturbative QCD calculations.

Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled $$p+p$$ collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to $$p+p$$ collisions.

Measurement of neutral mesons in $$p$$ + $$p$$ collisions at $$sqrt{s}$$ = 200 GeV and scaling properties of hadron production

The PHENIX experiment at RHIC has measured the invariant differential cross section for production of $$K^0_s$$, $$omega$$, $$eta'$$ and $$phi$$ mesons in $$p + p$$ collisions at $$sqrt{s}$$ = 200 GeV. The spectral shapes of all hadron transverse momentum distributions are well described by a Tsallis distribution functional form with only two parameters, $$n$$ and $$T$$, determining the high $$p_T$$ and characterizing the low $$p_T$$ regions for the spectra, respectively. The integrated invariant cross sections calculated from the fitted distributions are found to be consistent with existing measurements and with statistical model predictions.
