Abstract

The fast-rotating N=151 isotones ²⁴⁵Pu, ²⁴⁷Cm and ²⁴⁹Cf have been studied through inelastic excitation and transfer reactions with radioactive targets. While all have a ground-state band built on a νj_15/2[734]9/2^- Nilsson configuration, new excited bands have also been observed in each isotone. These odd-N excited bands allow a comparison of the alignment behavior for two different configurations, where the νj_15/2 alignment is either blocked or allowed. The effect of higher order deformations is explored through cranking calculations, which help clarify the elusive nature of νj_15/2 alignments.

Population and decay of a $K^{π} = 8^{-}$ two-quasineutron isomer in ${}^{244}{Pu}$

Journal Article Hota, S. S. ; Tandel, S. K. ; Chowdhury, P. ; ... - Physical Review C

Here, the decay of a K^π = 8^– isomer in ²⁴⁴Pu and the collective band structures populating the isomer were studied using deep inelastic excitations with ⁴⁷Ti and ²⁰⁸Pb beams, respectively. Precise measurements of M1/E2 branching ratios in the band confirm a 9/2^–[734]_νⓍ7/2⁺[624]_ν configuration assignment for the isomer, validating the systematics of K^π = 8^–, two-quasineutron isomers observed in even-Z, N = 150 isotones. These isomers around the deformed shell gap at N = 152 provide critical benchmarks for theoretical predictions of single-particle energies in this gateway region to superheavy nuclei.

D⁰-Meson R_AA in PbPb Collisions at $\sqrt{s_{N N}} = 5.02 TeV$ and Elliptic Flow in pPb Collisions at $\sqrt{s_{N N}} = 8.16 TeV$ with CMS

Journal Article Shi, Zhaozhong - Nuclear Physics. A

The study of charm production in heavy-ion collisions is considered an excellent probe for the properties of the hot and dense medium created in heavy-ion collisions. Measurements of D⁰-meson nuclear modification factor can provide strong constraints into the mechanisms of in-medium energy loss and charm flow in the medium. The measurement of D0-meson elliptic flow in pPb collisions helps us understand the strength of charm quarks coupling to significantly reduced systems which demonstrate hydrodynamic properties. In this paper, the measurements of the D⁰-meson nuclear modification factor in PbPb collisions at 5.02 TeV together with the new measurement of D⁰-meson ellipticmore »« less

Measurements of the $ϒ (1 S)$ , $ϒ (2 S)$ , and $ϒ (3 S)$ differential cross sections in pp collisions at $\sqrt{s} = 7 TeV$

Journal Article Khachatryan, V. ; Sirunyan, A. M. ; Tumasyan, A. ; ... - Physics Letters B

Differential cross sections as a function of transverse momentum p_T are presented for the production of Υ(nS) (n = 1, 2, 3) states decaying into a pair of muons. Thus, data corresponding to an integrated luminosity of 4.9 fb^-1 in pp collisions at √s = 7 TeV were collected with the CMS detector at the LHC. The analysis selects events with dimuon rapidity |y| < 1.2 and dimuon transverse momentum in the range 10 < p_T < 100 GeV. The measurements show a transition from an exponential to a power-law behavior at p_T ≈ 20 GeV for the three Υmore »« less

Search for Higgs boson pair production in the $γ γ b \overline{b}$ final state in pp collisions at $\sqrt{s} = 13 TeV$

Journal Article Sirunyan, A. M. ; Tumasyan, A. ; Adam, W. ; ... - Physics Letters B

A search is presented for the production of a pair of Higgs bosons, where one decays into two photons and the other one into a bottom quark–antiquark pair. The analysis is performed using proton–proton collision data at √s=13 TeV recorded in 2016 by the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9fb^-1. The results are in agreement with standard model (SM) predictions. In a search for resonant production, upper limits are set on the cross section for new spin-0 or spin-2 particles. For the SM-like nonresonant production hypothesis, the data exclude a product of cross sectionmore »« less
