Alpha particle clustering is thought to be widespread throughout the nuclear chart, and light nuclei provide an ideal testing ground for state-of-the-art theoretical calculations, such as the Algebraic Cluster Model (ACM) [1]. The predicted 2+ rotational excitation of the Hoyle State was first unambiguously measured using gamma beams and an Optical TPC detector [2]. To explore further...
The detailed properties of the 12C second 0+ excited state, known as the Hoyle state,
are both a challenge for nuclear structure theory and have a key role in the synthesis of the elements.
Theoretical calculations show different hypotheses regarding its spatial configuration but most of them predict a strongly developed 3α structure and a matter radius significantly larger than the ground...
Away from the beta-stability valley, when nuclei become unbound towards emission of two protons ($2p$), ground-state $2p$ radioactivity becomes possible and is a characterising decay mode for even-$Z$ elements beyond the $2p$ drip-line. It is this a very exotic decay mode, so far observed experimentally only for a handful of cases, for light and medium-mass isotopes with $Z \leq 36$ [1,2]....
Nuclei that present a three-body character have attracted particular interest over the past few decades. Of particular relevance is the case of two-neutron halo nuclei, e.g., ⁶He, ¹¹Li or ¹⁴Be, which exhibit exotic features in nuclear collisions. These are Borromean systems, or three-body systems in which all binary subsystems cannot form bound states. The correlations between the valence...
Femtoscopy is traditionally used to determine the size of the particle emitting region in heavy-ion collisions. The non-identical particle femtoscopy is additionally able to measure the difference in average emission points (so-called emission asymmetry) between two types of particles. This asymmetry is sensitive to details of the dynamics of the system created in the collision, and depends on...
The interaction between charged kaons and (anti-)deuterons has been a missing piece of information in the field of the low-energy (anti-)kaon-nucleon interactions for more than 40 years. So far, the only experimental studies of the strong interaction have come from scattering experiments that provided the scattering cross sections at intermediate momenta. Specific information on the strong...
Several high-precision experiments at the Antiproton Decelerator complex at CERN aim to look for any significant differences between matter and antimatter. One of these experiments is AEgIS, whose primary goal is to test the weak equivalence principle for antimatter by measuring (with atomic accuracy) the free fall of a neutral antihydrogen atom in the Earth's gravitational field. It turns out...
The production mechanism of light (anti)nuclei in hadronic collisions, despite the several experimental results from low collision energies at the AGS and GSI to high energies at RHIC and at the LHC, is still mysterious and under intense debate in the scientific community. The experimental measurements can be described by two competing phenomenological models, the statistical hadronization...
Measurements at the LHC have provided evidence for collective behavior in high-multiplicity proton-proton (pp) and proton-lead (pPb) collisions through multiparticle correlation techniques. To investigate detailed properties of this collectivity, a comprehensive study of differential Fourier coefficients ($v_{n}$) in particle transverse momentum ($p_\mathrm{T}$) and event multiplicity is...
Recently, we have found a new and finite, exact family of solutions of 1+1 dimensional relativistic hydrodynamics with accelerating velocity field. After reviewing some earlier application, I present a new analytic formula derived from the mentioned family of solutions that describes the thermal photon radiation in high energy heavy ion collisions. I compared this new formula to the most...
Why physics, which is considered objective and not affected by who is doing the research, teaching and learning, is so dominated by men?
Why do so many groups of people decide not to come to physics, or to leave this field?
How do we make physics or scientific institutions more welcoming and inclusive for a larger part of the population?
