The ALICE collaboration, S. Acharya, D. Adamová, S. P. Adhya, more

Journal of High Energy Physics > 2019 > 2019 > 9 > 1-22

Abstract Two-particle correlations in high-energy collision experiments enable the extraction of particle source radii by using the Bose-Einstein enhancement of pion production at low relative momentum q ∝ 1/R. It was previously observed that in pp collisions at s $$ \sqrt{s} $$ = 7TeV the average pair transverse momentum k_T range of such analyses is limited due to large background correlations...

S. M. Cha, K. Y. Chae, M. J. Kim, M. S. Kwag, more

Journal of the Korean Physical Society > 2018 > 73 > 8 > 1055-1060

The α-clusterization of an atomic nucleus has been studied for a long time, even from the earliest days of nuclear physics. Our understanding of the α-cluster structure is, however, mainly limited to the self-conjugate A = 4n (n = 2, 3, 4, · · · ) light nuclei and some of the neutron-rich radionuclides such as ¹⁰Be, ¹¹B, and ¹⁴C. In order to study the α-cluster structure of a neutron-deficient ²²Mg...
