After measuring in 2012 a relatively large value of the neutrino mixing angle θ13, the door is now open to observe for the first time a possible CP violation in the leptonic sector. The measured value of θ13 also privileges the 2nd oscillation maximum for the discovery of CP violation instead of... -

The targeted treatment of cancerous tumors by alpha-emitting radionuclides has shown remarkable efficacy in recent clinical trials [1]. It is likely that this treatment option will ultimately be applicable to a wide range of cancers and other diseases, subject to the development of specific carrier molecules.

Open-charmed mesons are unique tools to study the properties of the Quark-Gluon Plasma (QGP) formed in ultra-relativistic nucleus-nucleus collisions. Charm quarks, due to their large mass, are produced in hard partonic scattering processes in the initial stages of the collision. Therefore, they experience all the phases of the QGP evolution propagating through the medium and interacting with...

After introductory presentation of the underlying idea of varying constants cosmologies I will explain how this idea can lead to toy cyclic models of the parallel universes (the multiverse) with different evolution of the fundamental constants and same geometry using the condition that the total entropy of the system does not decrease. Then, I will describe how to use the second quantization...

The decay K+→π+𝑣𝑣̅, with a very precisely predicted branching ratio of less than 10-10, is one of the best candidates to reveal indirect effects of new physics at the highest mass scales. The NA62 experiment at the CERN SPS is designed to measure the branching ratio of the K+→π+𝑣𝑣̅ with a decay-in-flight technique. NA62 took data so far in 2016-2018. Statistics collected in 2016 allowed NA62...

Final states containing both leptons and jets can be used to probed for physics beyond the Standard Model. Searches for new physics models with these signatures, such as heavy neutrinos or leptoquarks for example, are performed using the ATLAS experiment at the LHC. The results of the most recent searches on 13 TeV pp data will be presented.

The Pierre Auger Observatory is the world's largest detector for extensive air showers initiated by cosmic rays with energies above $3\times10^{17}\,\mathrm{eV}$. The main objectives of the Observatory are the measurement of the energy spectrum up to the highest energies, the determination of the mass composition and the search for the origin of the ultra-high energy particles. The manifold...

The NA48/2 experiment at CERN reports the first observation of the K± → π± π0 e+ e− decay from an exposure of 1.7×10^11 charged kaon decays recorded in 2003−2004. A sample of 4919 candidates with 4.9% background contamination allows the determination of the branching ratio in the full kinematic region. The study of the kinematic space shows evidence for a structure dependent contribution in...

The High School Project on Astrophysics Research with Cosmics (HiSPARC) is a large extensive air shower (EAS) array with detection stations throughout the Netherlands, United Kingdom, Denmark and Namibia. The majority of detection stations is hosted by high schools. A HiSPARC station consists of two or four scintillators with PMTs placed inside roof boxes on the rooftop of a building. Next to...

The role played by non extensive thermodynamics in physical systems has been under intense debate for the last decades. With many applications in several areas, the Tsallis statistics [1] has been discussed in details in many works and triggered an interesting discussion on the most deep meaning of entropy and its role in complex systems. Some possible mechanisms that could give rise to non...

Many theories beyond the Standard Model predict new phenomena, such as Z' and W' bosons, in final states with isolated, high-pt leptons (e/mu/nu). Searches for new physics models with these signatures are performed using the ATLAS experiment at the LHC. The recent 13 TeV pp results will be reported.

Precise measurements of the branching ratios (BRs) for the flavor-changing neutral current decays K→π𝑣𝑣̅ can provide unique constraints on CKM unitarity and, potentially, evidence for new physics. It is important to measure both decay modes, K+→π+𝑣𝑣̅ and KL→π0𝑣𝑣̅, since different new physics models affect the rates for each channel differently. The NA62 experiment at the CERN SPS is currently...

Core-collapse supernovae are one of the most fascinating phenomena in astrophysics but the explosion mechanism is not clearly understood yet because of their intricacies. I will give an overview about the role of nuclei and nuclear physics uncertainties in supernovae. I will also discuss key nuclei and their key information to be investigated for further supernova study, and introduce recent...

Given an observable and its operator product expansion (OPE), we present expressions that carefully disentangle truncated sums of the perturbative series in powers of α from the non-perturbative (NP) corrections. This splitting is done with NP power accuracy. Analytic control of the splitting is achieved and the organization of the different terms is done along an super/hyper-asymptotic...

Sexaquarks are a hypothetical low mass, small radius uuddss dibaryon which has been proposed recently and especially as a candidate for Dark Matter [1]. The low mass region below 2 GeV escapes upper limits set from experiments which have searched for the uuddss dibaryon and did not find it [1].
Depending on its mass, such state may be absolutely stable or almost stable with decay rate of...

Measurements of the inclusive and differential top-quark pair production cross sections in proton-proton collisions at a centre-of-mass energy of 13 TeV with the ATLAS detector at the Large Hadron Collider are presented. The investigated final states include $t\bar{t}$+jets as well as $t\bar{t}$+heavy flavour jets. The differential measurements reach high precision and are compared to the best...

DEAP-3600 is a single-phase liquid argon (LAr) direct-detection dark matter experiment, operating 2km underground at SNOLAB (Sudbury, Canada). The 3279kg of LAr are contained in a spherical acrylic vessel surrounded by 255 eight-inch photomultiplier tubes (PMTs). Analysis of the data taken during the first year of operation resulted in the most sensitive limit on the spin-independent...

Diffractive, elastic and precision total pp cross-section RENORM-model predictions confront experimental results at the LHC. Discrepancies among different results are a puzzle that RENORM helps decipher. Possible Odderon contributions to elastic scattering and thereby to the discrepancies-puzzle are discussed.

Mathematically rigorous derivation of a system of equations to describe the hadron resonance gas equation of state within the induced surface tension and with the induced surface and curvature tensions approaches is worked out. Such an equation of state allows one to go beyond the Van der Waals approximation for the interaction potential of hard spheres. The compressibility of a single- and...
