In heavy-ion collisions (A-A) at the CERN Large Hadron Collider (LHC) energies, a strongly coupled Quark Gluon Plasma (QGP) is produced which gives rise to collective phenomena whose signatures can be retrieved in final state hadronic observables. Recent observations in small systems, such as pp collisions, show remarkable similarities among these systems, which are highly suggestive of the...

The relativistic heavy ion collisions represent an arena for the probe of various anomalous transport effects. Those effects, in turn, reveal the correspondence between the solid state physics and the high energy physics, which share the common formalism of quantum field theory. It may be shown that for the wide range of field - theoretic models the response of various nondissipative currents...

In this work we present a comparative study of PYTHIA, EPOS, QGSJET and SIBYLL generators for proton-proton collisions at $\sqrt{s}$ = 7 TeV in the forward region. The generated charged energy flow, charged-particle distributions, charged-hadron production ratios and $V^{0}$ ratios are compared to the forward physics measurements from LHCb and TOTEM. Most of the observed differences seem to be...

Muon radiography is an imaging technique based on the measurement of the absorption of cosmic ray muons. This technique has recently been used successfully to investigate the presence of unknown cavities in the Galleria Borbonica in Naples and in the Cheops Pyramid at Cairo.

The MIMA detector (Muon Imaging for Mining and Archeology) is a muon tracker prototype for the application of muon...

The neutron time-of-flight (n_TOF) facility of CERN, based on an idea by C. Rubbia et al., became operative in 2001 and since then it occupies a major role in the field of neutron cross-section measurements. Neutron-induced reactions play a key role in several aspects of nuclear physics, from nuclear technology, where they enter in reactor calculations and design, to nuclear astrophysics and...

The TOTEM experiment at the LHC has measured proton-proton elastic scattering in dedicated runs at √s = 2.76, 7, 8 and 13 TeV centre-of-mass

LHC energies. The proton-proton total cross-section σtot has been derived for each energies using a luminosity independent method. TOTEM has

excluded a purely exponential differential cross-section for elastic proton-proton scattering with significance...

We propose, for the first time, the potential of physics opportunities at the ProtoDUNE detectors in the context of dark matter physics. More specifically, we explore various experimental signatures at the cosmic frontier, arising in boosted dark matter scenarios, i.e., relativistic, inelastic scattering of boosted dark matter often created by the annihilation of its heavier component which...

Non-perturbative techniques are needed to study strongly coupled systems. One powerful approach is the n-particle irreducible effective action. The technique provides a systematic expansion for which the truncation occurs at the level of the action. However, renormalisation using a standard counterterm approach is not well understood. At the 2PI level one must introduce multiple counterterms,...

We show that in no-scale models in string theory, the flat, expanding cosmological evolutions found at the quantum level can be attracted to a "quantum no-scale regime" (QNSR), where the no-scale structure is restored asymptotically. In this regime, the quantum effective potential is dominated by the classical kinetic energies of moduli fields. To be specific, we find that all initially...

Primordial black holes can be seeded by large cosmological fluctuations produced during inflation. This happens if the potential for inflation is sufficiently flat in some regions. However, in such regions, the dynamics of the inflaton is dominated by quantum diffusion rather than by classical slow roll. This implies that the standard method to calculate the amplitude of the fluctuations,...

We calculate a finite momentum-dependent part of the photon polarization operator in a simple model of Lorentz-violating quantum electrodynamics nonperturbatively at all orders of Lorentz-violating parameters. We sum one-particle reducible diagrams into the modified photon propagator, and determine the physical photon dispersion relation as the location of its pole. The photon dispersion...
