Synthesis of superheavy elements: Uncertainty analysis to improve the predictive power of reaction models

2016-09-28T10:00:00-04:00

Author(s): Hongliang Lü, David Boilley, Yasuhisa Abe, and Caiwan Shen
Background: Synthesis of superheavy elements is performed by heavy-ion fusion-evaporation reactions. However, fusion is known to be hindered with respect to what can be observed with lighter ions. Thus some delicate ambiguities remain on the fusion mechanism that eventually lead to severe discrepanc…

Kinematic sensitivity to the Fierz term of β-decay differential spectra

2016-09-28T10:00:00-04:00

Author(s): M. González-Alonso and O. Naviliat-Cuncic
The current most stringent constraints on exotic scalar or tensor couplings in neutron and nuclear β decay, involving left-handed neutrinos, are obtained from the Fierz interference term. The sensitivity to this term in a correlation coefficient is usually driven by an energy-averaged kinematic fact…

Neutrino-induced reactions on nuclei

Author(s): K. Gallmeister, U. Mosel, and J. Weil
Background: Long-baseline experiments such as the planned deep underground neutrino experiment (DUNE) require theoretical descriptions of the complete event in a neutrino-nucleus reaction. Since nuclear targets are used this requires a good understanding of neutrino-nucleus interactions.

Measurement of elliptic flow of light nuclei at sqrt[s_{NN} ] =200, 62.4, 39, 27, 19.6, 11.5, and 7.7 GeV at the BNL Relativistic Heavy Ion Collider

2016-09-23T10:00:00-04:00

Author(s): L. Adamczyk et al. (STAR Collaboration)
We present measurements of second-order azimuthal anisotropy (v_{2}) at midrapidity (|y|<1.0) for light nuclei d,t,^{3}He (for sqrt[s_{NN}]=200, 62.4, 39, 27, 19.6, 11.5, and 7.7 GeV) and antinuclei d[over ¯] (sqrt[s_{NN}]=200, 62.4, 39, 27, and 19.6 GeV) and ^{3}He[over ¯] (sqrt[s_{NN}]=200 GeV) in the STAR (Solenoidal Tracker at RHIC) experiment. The v_{2} for these light nuclei produced in heavy-ion collisions is compared with those for p and p[over ¯]. We observe mass ordering in nuclei v_{2}(p_{T}) at low transverse momenta (p_{T}<2.0 GeV/c). We also find a centrality dependence of v_{2} for d and d[over ¯]. The magnitude of v_{2} for t and ^{3}He agree within statistical errors. Light-nuclei v_{2} are compared with predictions from a blast-wave model. Atomic mass number (A) scaling of light-nuclei v_{2}(p_{T}) seems to hold for p_{T}/A<1.5GeV/c. Results on light-nuclei v_{2} from a transport-plus-coalescence model are consistent with the experimental measurements.

Using Penning trap mass spectrometry, we have performed a precise determination of the Q value for the highly forbidden β decay of ^{113}Cd. An independent measurement of the Q value fixes the end-point energy in a fit to the ^{113}Cdβ-decay spectrum. This provides a strong test of systematics for d…
