Dileptons produced during heavy-ion collisions represent a unique probe of the QCD phase diagram, and convey information about the state of the strongly interacting system at the moment their preceding off-shell photon is created. In this study, we compute thermal dilepton yields from Au+Au collisions performed at different beam energies, employing...
We investigate yields, elliptic flow $v_2$, baryon-to-meson ratios, and correlations of various charmed hadrons in high energy proton-proton ($pp$) collisions, employing the newly developed EPOS4HQ approach, which reproduces basic experimental data concerning light hadrons. All the above-mentioned heavy flavor observables can be well explained, ess...

The Cosmic Neutrino Background (CNB) encodes a wealth of information, but has not yet been observed directly. To determine the prospects of detection and to study its information content, we reconstruct the phase-space distribution of local relic neutrinos from the three-dimensional distribution of matter within 200 h -1 Mpc of the Milky Way. Our a...
The measurement of the absolute neutrino mass scale from cosmological large-scale clustering data is one of the key science goals of the Euclid mission. Such a measurement relies on precise modelling of the impact of neutrinos on structure formation, which can be studied with $N$-body simulations. Here we present the results from a major code compa...

We consider the physical implications of very light axiodilatons motivated by a novel mechanism to substantially reduce the vacuum energy proposed in 2110.10352. We address the two main problems concerning the light axiodilaton that appears in the low-energy limit, namely that the axion has a very low decay constant fa ∼ eV (as read from its kineti...

Conservation laws have many applications in numerical relativity. However, it is not straightforward to define local conservation laws for general dynamic spacetimes due the lack of coordinate translation symmetries. In flat space, the rate of change of energy-momentum within a finite spacelike volume is equivalent to the flux integrated over the s...

The relationship between human and cosmos is still quite a mystery. The ancient intuition about interconnectedness of human and cosmos was replaced by a worldview in which human is part of nature primarily through the continuity of the body with the outer nature. The mind is seen as a unique phenomenon mysteriously emerging from matter. To this mys...
I view most aspects of life as being made up of tiny particles of matter that come together and synthesize to shape both our individual and collective human existence. Delicate threads are intricately woven together forming textiles and fabric. Tiny cellular particles shape all living species. Devices of human invention are mapped and constructed t...

The measurement of neutrino magnetic moment larger than 10-19 μB would be a clear signature of physics beyond the standard model other than the existence of massive Dirac neutrinos. The use of a spherical proportional counter detector filled with gas at 40 bar located near a nuclear reactor would be a simple way to perform such a measurement exploi...

The paper argues that Plessner’s theory of positionality can be traced back to Kant’s theory of predicabilia in the Critique of Pure Reason. Kant’s theory of predicabilia allows for the reformulation of Plessner’s distinction between the organic structure of the living body on the one hand and the positional unity of this living body on the other h...
