Despite the great achievement of the discovery of the Higgs boson, the Large Hadron Collider has found no evidence of physics Beyond the Standard Model and the exclusion limits on new physics have now become pretty strong. The LNF Winter Institute 2018 will discuss the prospects to discover new physics at the present LHC run, in its high-luminosity and high-energy phases, as well as at other future colliders. In particular, we shall debate the searches for Z’ bosons, predicted by U(1) gauge groups inspired by Grand Unification Theories, taking particular care about supersymmetric and leptophobic scenarios and Dark Matter signature in models based on extended Higgs sectors, possibly CP-violating. We will also investigate the perpectives at future circular colliders from the viewpoint of Higgs and top-quark phenomenology.

## Studying the properties of domain wall network as QCD vacuum

The general underlying purpose of this study is a renement of understanding the mechanism of connement in quantum chromodynamics (QCD) within the approach based on the specic background vacuum gluon congurations { almost everywhere homogeneous Abelian gluon elds represented by the statistical ensemble of domain wall networks. In particular, the aim of the present study is to investigate the role of quark low-lying modes in the presence of these background elds for stabilization of a nite size of a space-time regions (domains) where the background (anti-)self-dual Abelian eld can be seen as homogeneous. This task is of principal importance for justication of the domain model of connement, chiral symmetry realization and colorless hadron formation in QCD. This estimation indicates that, based solely on the requirement of minimal energy, the quark zero modes may provide for a self- consistent mechanism of formation of the domain structured vacuum gluon congurations.The regular solution of the problem related to explicit evaluation of the energy of the Abelian (anti-self-)dual domain with nite size, that is also formulated in this work but not yet solved, can lead to the very interesting mechanism of the domain size stabilization due to the quasi-zero modes of the quark elds in the (anti-) self-dual background.

Transverse observables in colour-singlet hadro-production, like the Higgs transverse momentum in gluon fusion or the $\phi*$ angle in Drell-Yan processes, provide a clean experimental and theoretical environment for precision physics at colliders. I will discuss a new method for performing the resummation of transverse observables in momentum space up to N3LL accuracy.

## Constraining Extended Gravity Theories by Solar System satellites

We consider Extended Theories of Gravity and in particular, models containing scalar-tensor and higher-order curvature terms, as well as models derived from fundamental theories like Non-commutative Spectral Geometry. In the weak-field approximation, we take into account the geodesic and Lense-Thirring processions, deriving constraints on the free parameters by the experimental data on Solar System scales. The main result of this research is that constraints on fundamental theories of gravity can be achieved at local scales and compared with cosmic data.

Pseudoscalar QCD axions and axion-like Particles (ALPs) are an excellent candidate for Dark Matter or can act as a mediator particle for Dark Matter. A look at the allowed axion/ALP parameter space makes it clear that these might exist at low mass (below few eV), as (part of) Dark Matter. Alternatively they might exist at higher mass, above roughly the MeV scale, potentially as a Dark Matter mediator particle. In this talk I review most prominent techniques and experiments searching for Axions and ALPs and will present in more detail efforts taking place at CERN.

On August 17th, 2017, a new era in the multi-messenger astronomy has started. The detection of gravitational waves produced by the merging of two neutron stars with three detectors (the two Advanced LIGO and Advanced VIRGO) has allowed the source localization, making possible the observation of the electromagnetic follow-up by many telescopes around the world. This mini-workshop will deal with the detection of the event as well as with its scientific impact on different fields, ranging from gravitational waves to astrophysics.

We propose a model for dark matter, which in principle ONLY use the Standard Model, although it only works under use of speculated NONPERURBATIVE effects. In this model the dark matter consists of insect sized pearls or better bubbles made from a different phase of vacuum (“condensate vacuum”) consisting of a fluid of top and anti top quarks – likely in the form of bound states of 6 top + 6 anti top quarks – pumped up by usual atoms under very high pressure to compensate the very strong surface tension of the bubbles. We take as fitted values of the size of the bubbles a diameter of 1 cm and a mass of $10^8$ kg, and correspondingly the distance between the individual bubbles is between our distance to the moon and to the sun. Impacts – one about every century – would fit with causing the special type of volcanoes called kimberlite pipes, of which there are about 6500 known on the earth. In the supernova SN1987A in the Large Margellanic Cloud there were observed a controversial neutrino signal in Mont Blanc by LSD about 5 hours before the main neutrino burst observed later; this is speculated to be due to our pearls.
