When antimatter meets strangeness: a new era for precision hypernuclear physics

Project description

Production mechanism to advance hypernuclear physics

Nuclear and hypernuclear physics are vital for understanding the universe. Current research focuses on hadronic matter and hyperons, but our knowledge remains limited to nucleon scattering and nuclear data, lacking precision on other quark flavours. The ERC-funded HYPER project will develop a revolutionary production mechanism of hypernuclei from antimatter. This solution will enable the use of spectroscopy of single-lambda hypernuclei along isotopic chains and the measured precision of ground-state properties to study previously inaccessible isospin properties of many-body interactions involving lambda hyperons, providing key insights into the role of strangeness in nuclear equations of state and neutron stars.

Objective

Observable hadronic matter is mostly composed of u, d quarks. The strangeness degree of freedom is expected to play an important role in dense nuclear matter in the form of hyperons, baryons with at least one valence strange quark. Hyperons can form bound nuclear systems
with nucleons and create short-lived hypernuclei which decay on the time-scale of the weak interaction (typically ∼200 ps). Our knowledge of nuclear matter is so far restricted to precision nucleon scattering and nuclear data while a generalisation to other quark flavours lacks precision data.

HYPER pioneers a new production mechanism of hypernuclei from antimatter. 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.

The core of HYPER is the development of a new multi-purpose detector with high sensitivity, energy and timing resolutions to be used at the Antimatter Factory of CERN. HYPER has the potential to seed a hypernuclei factory in Europe.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
