Abstract

Many theories beyond the standard model of particle physics predict the existence of weakly-coupled exotic spin-dependent interactions between standard model particles. We use experimental upper bounds on neutron-nucleus parity violation at meV and keV neutron energies in the forward scattering limit described by neutron optics to constrain exotic parity-odd interactions of the neutron with nucleons from exotic vector boson exchange for force ranges between $10^{-2}$ to $10^{-14}$ meters.

Sizeable mixing between the coexisting normal and intruder structures of $^{96}$Zr revealed through lifetime measurements

Lifetimes of excited states of the nucleus $^{96}$Zr were studied with the Doppler-shift attenuation method following the $^{94}$Zr($^{18}$O,$^{16}$O)$^{96}$Zr two-neutron transfer reaction. The obtained $B(E2;2^+_2\to0^+_2)$ and $B(E2;4^+_1\to2^+_2)$ transition strengths, amounting to $26(2)$ and $39(7)$\,W.u., respectively, firmly attribute the $2^+_2$ and $4^+_1$ states to the collective intruder band built on top of the $0^+_2$ state. The nature of this structure is discussed against predictions of the collective model using the Bohr Hamiltonian, the interacting boson model with configuration mixing, and the quasiparticle vacua shell model. The collective, interband $B(E2;4^+_1\to2^+_1)=11.2(8)$\,W.u. transition strength, refuting the previously assumed purity of both structures, is reproduced in the calculations. The quasiparticle vacua shell model predicts, in agreement with a simple two-state model based on experimental $E2$ transition strengths, considerable mixing between the normal and intruder $2^+$ states.

Search for $^4\overline{\mathrm{Li}}$ from $\overline{\mathrm{p}}+{}^3\overline{\mathrm{He}}$ femtoscopy in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}} =5.36$ TeV with ALICE

In these proceedings, the search for $^4\overline{\mathrm{Li}}$ in Pb-Pb collisions with ALICE is presented. The particle is reconstructed via its two-body decay channel $^4\overline{\mathrm{Li}} \rightarrow \overline{\mathrm{p}} + {}^3\overline{\mathrm{He}}$, using femtoscopic correlations. A dedicated analysis procedure has been developed to subtract the correlated and uncorrelated $\overline{\mathrm{p}} + ^3\overline{\mathrm{He}}$ combinatorial background. The production yield of $^4\overline{\mathrm{Li}}$ is compared with that of $^4\overline{\mathrm{He}}$. Owing to the presence of several $^4\mathrm{Li}$ resonances and their spin degeneracy, the production of $^4\overline{\mathrm{Li}}$ is expected to be enhanced with respect to the compact $^4\overline{\mathrm{He}}$, making this new measurement a sensitive probe for testing nucleosynthesis models in high-energy hadronic collisions.

Short-range correlated pair formation and nuclear shell structure

Short-range correlated (SRC) nucleon pairs, caused by brief, high-momentum interactions between two nucleons, are dominated by neutron-proton pairs with large relative and smaller center-of-mass momenta. However, which nucleons form pairs is not fully understood. Measurements of 40,48Ca and 54Fe showed that intra-shell pairing was much stronger than inter-shell pairing. We measured high- missing-momentum protons knocked out in electron scattering from selected nuclei with a range of shell configurations, A, and N/Z, including 9Be, 10,11B, 12C, 40,48Ca, 54Fe, and 197Au, focusing on the four light nuclei. Unexpectedly, we found that adding one proton to 9Be (to make 10B) increased the number of correlated protons far more than adding one neutron to 10B or adding one proton to 11B, perhaps due to the large spin (J = 3) of 10B or the unusual structure of 9Be. In addition, the increase in pairing probability from 9Be to 12C and from 40Ca to 54Fe was much steeper than the increase from 9Be to 197Au. This shows the importance of low-momentum nuclear structure on the probability of high-momentum nucleon pairing.
