Abstract

The inclusive 2H(3He,t) reaction has been studied at 2 GeV for energy transfers up to 500 MeV and scattering angles from 0.25 up to 4 degrees. Data are well reproduced by a model based on a coupled-channel approach for describing the NN and N Delta systems. The effect of final state interaction is important in the low energy part of the spectra. In the delta region, the cross-section is very sensitive to the effects of Delta-N interaction and Delta N - NN process. The latter has also a large influence well below the pion threshold. The calculation underestimates the experimental cross-section between the quasi-elastic and the delta peaks; this is possibly due to projectile excitation or purely mesonic exchange currents.

Neutron Optical Constraints on Exotic Parity-odd Interactions between Neutrons and Nucleons

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.
