No full textLHCb Recent studies of open charm production in small systems at LHCb
No full textThe forward geometry and precision instrumentation of the LHCb spec- trometer provides unique insights into the production of heavy quarks at the LHC. Heavy quark production in pPb collisions are sensitive to the modification of nuclear parton distribution functions, energy loss in the nucleus, and the hadronization process, among other effects. In this talk, precision measurements of open charm production from a rich set of charmed hadrons in pPb collisions at 5.02 and 8.16 TeV will be presented, including new LHCb measurements of D mesons and Ξc baryons in pp and pPb collisions. Comparisons with theoretical models and related results will be discussed
HYPER: a single-Lambda hypernuclei factory at the Antimatter-Factory
No full textHYPER aims at pioneering the production of hypernuclei from low-energy antiprotons at the Antimatter Factory, CERN. HYPER will explore the terra incognita of the strange nuclear landscape with unprecedented capabilities. The measured precision ground-state properties and spectroscopy of single-Lambda hypernuclei along isotopic chains, from neutron deficient to neutron rich, will give access to the isospin properties of the many-body interactions involving Lambda hyperons, and thus to the role of strangeness in the nuclear equation of state and in neutron stars. In the present Letter of Intent, the motivations of HYPER and the intended concept are described

The atomic nucleus as a window to new physics
No full textAnswers to some of the most fundamental questions in science, such as the mass and character of the neutrino, the nature of dark matter, or the abundance of matter over antimatter, might very well reside in the physics of the atomic nucleus. As the role of nuclei in unraveling such mysteries continues to deepen, first-principles quantum simulations, beginning from only underlying nuclear/weak forces, are currently undergoing nothing short of a revolution. Long considered a collection of disconnected phenomenological models, breakthroughs in our treatment of nuclear forces rooted in QCD, the strongly interacting many-body problem, and AI/machine learning techniques are transforming modern nuclear theory into a true first-principles discipline.
In this talk I will outline this next-generation "ab initio" philosophy and spotlight several recent milestones for nuclear structure/astrophysics, including statistical predictions of the limits of nuclei as well as the neutron skin of 208Pb to constrain neutron star properties. I will then focus on our parallel advances driving first ab initio predictions of neutrinoless double-beta decay, WIMP- and neutrino-nucleus scattering, and symmetry-violating moments, with quantifiable uncertainties, for essentially all nuclei relevant in searches for new physics.</p
