Heavy quarks (charm and beauty) are a powerful tool to study the properties of the Quark-Gluon Plasma (QGP), the hot and dense medium formed in high-energy heavy-ion collisions. Due to their large masses, heavy quarks are produced in hard partonic scattering processes in the initial stages of the collision. Therefore, they experience the whole system evolution interacting with the medium...

Measurements of the inclusive and differential cross-sections for top-quark pair and single top production cross sections in proton-proton collisions with the ATLAS detector at the Large Hadron Collider are presented at center-of-mass energies of 8 TeV and 13 TeV. The inclusive measurements reach high precision and are compared to the best available theoretical calculations. These...

The production of jets and prompt isolated photons at hadron colliders provides a stringent test of perturbative QCD at the highest energies. The process can also be used to probe the proton structure.

Due to strong enhancement of loop effects in a superstrong magnetic field ($B\gg m^2/e^3$) the Coulomb potential becomes screened. This phenomenon dramatically changes the dependence of the electron energy levels on magnetic field. In particular, the freezing of energy levels occurs so the ground energy level of light ions can never reach the lower continuum (become critical), no matter how...

The increase of hadronic production as a function of multiplicity in proton-proton and proton-lead collisions is considered as an interesting observable to study multi-parton interactions. The correlation between J/$\Psi$ production and multiplicity has been studied in pp collisions at $\sqrt{s} = 7$ and 13 TeV and p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV by ALICE. An increase of...

Run-2 of the LHC has provided new challenges to track and vertex reconstruction with higher centre-of-mass energies and luminosity leading to increasingly high-multiplicity environments, boosted, and highly-collimated physics objects. To achieve this goal, ATLAS is equipped with the Inner Detector tracking system built using different technologies, silicon planar sensors (pixel and...

Energy tensor of the continuous nonempty space in the pure field physics of Einstein and Infeld is described by the analog of the Einstein equation for nondual matter. The modified Einstein equation results in the vector geodesic consequences for material 4-flows of scalar Ricci densities. Nonrelativistic 3-flows of these mass-energies modify the Navier-Stocks equation by the 1738 Bernoulli...

Production of Quark Gluon Plasma (QGP) has been established in central heavy ion collisions (Au+Au, Cu+Cu) at RHIC energies. Observation of strong suppression of hadron yields at high transverse momentum served as one of the most important evidences in favor of production of a new state of matter in such collisions. Recent RHIC run with asymmetric collision system (Cu+Au) provides the means to...

Quantum simulators promise to give rise to new insights into dynamical and static properties of complex quantum systems, beyond what is available on classical supercomputers. There is already some good evidence that quantum simulators have the potential to outperform classical computers. Yet, in order to be prone against arguments claiming a lack of imagination, this superior computational...

The AMADEUS collaboration is aiming to study the K$^-$ hadronic interaction with light nuclei in the low-energy regime with high precision. The main goal is to provide information on the $\bar{\mathrm{K}}$N interaction in nuclear medium, fundamental for the understanding of the non-perturbative QCD in the strangeness sector, with implications going from nuclear physics to astrophysics....

The OPERA experiment reached its main goal by proving the appearance of $\nu_{\tau}$ in the CNGS $\nu_{\mu}$ beam. A total sample of 5 candidates fulfilling the analysis defined in the proposal was detected with a S/B ratio of about ten allowing to reject the null hypothesis at 5.1 $\sigma$. The search has been extended to $\nu_{\tau}$-like interactions failing the kinematical analysis defined...

The LHCf collaboration has successfully completed at the end of 2016 the main part of its measurement campaign of neutral particles produced in the forward direction at the Large Hadron Collider. The main purpose of these measurements is to provide the Cosmic Ray and High Energy Physics communities with a missing unique set of information for the improvement of the hadronic interaction models...

Direct dark matter searches are promising techniques to identify the nature of dark matter particles. A variety of experiments have been developed over the past decades, aiming to detect Weakly Interactive Massive Particles (WIMPs) via their scattering in a detector medium. Exploiting directionality would also give a proof of the galactic origin of dark matter making it possible to have a...
