Analysis of spectroscopic factors in $^{11}\mathrm{Be}$ and $^{12}\mathrm{Be}$ in the Nilsson strong-coupling limit


Author(s): A. O. Macchiavelli, H. L. Crawford, C. M. Campbell, R. M. Clark, M. Cromaz, P. Fallon, M. D. Jones, I. Y. Lee, and M. Salathe

Spectroscopic factors in $^{10}\mathrm{Be}$, $^{11}\mathrm{Be}$, and $^{12}\mathrm{Be}$, extracted from $(d,p)$, one-neutron knockout, and $(p,d)$ reactions, are interpreted within the rotational model. Assuming that the ground state and first excited state of $^{11}\mathrm{Be}$ can be associated wi...

Survival-mediated capture and fusion cross sections for heavy-element synthesis


Author(s): L. Yao and W. Loveland

The cross section for producing a heavy evaporation residue ${σ}_{\mathrm{EVR}}$ in a fusion reaction can be written as a product of three nonseparable factors, i.e., the capture cross section, the fusion probability ${P}_{\mathrm{CN}}$, and the survival probability ${W}_{\text{sur}}$. Each of these...

Anisotropic-hydrodynamics approach to a quark-gluon fluid mixture


Author(s): Wojciech Florkowski, Ewa Maksymiuk, and Radoslaw Ryblewski

The anisotropic-hydrodynamics framework is used to describe a mixture of quark and gluon fluids. The effects of quantum statistics, finite quark mass, and finite baryon number density are taken into account. The results of anisotropic hydrodynamics are compared with exact solutions of the coupled ki...

Relating centrality to impact parameter in nucleus-nucleus collisions


Author(s): Sruthy Jyothi Das, Giuliano Giacalone, Pierre-Amaury Monard, and Jean-Yves Ollitrault

In ultrarelativistic heavy-ion experiments, one estimates the centrality of a collision by using a single observable, say $n$, typically given by the transverse energy or the number of tracks observed in a dedicated detector. The correlation between $n$ and the impact parameter $b$ of the collision ...

Hanbury-Brown–Twiss (HBT) quantum correlations between identical hadrons provide information about the space-time evolution of the matter created in high-energy collisions of atomic nuclei. This paper reports on HBT measurements of charged pions created in proton-lead collisions at the LHC. The ATLAS Collaboration finds that even when one of the colliding partners is a proton, rather than a large nucleus, hallmarks of collectivity are seen, similar to those associated with the quark-gluon plasma produced in lead-lead collisions at the LHC: the HBT source size increases with multiplicity and decreases with transverse momentum of the pair.

Determination of the proton spin structure functions for $0.05<{Q}^{2}<5\phantom{\rule{0.16em}{0ex}}{\mathrm{GeV}}^{2}$ using CLAS


Author(s): R. G. Fersch et al. (CLAS Collaboration)

The basic properties of the proton, the lightest baryon, are determined by its quark and gluon composition. In particular, its spin of ħ/2 has been a challenge to understand in terms of the proton’s constituents. The comprehensive results presented here are based on measurements with high precision and dense kinematic coverage carried out with the CLAS detector at Jefferson Lab. They provide new insight into the proton substructure at resolutions on the length scale of the whole nucleon down to the quark level. A variety of strong interaction models are tested with these new data, to further constrain the quark and gluon contribution to the proton spin.
