## Resummation of transverse observables at LHC

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.

## Axions across different mass scales

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.

## LNF Mini-Workshop Series: Multi-messenger Astronomy

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.

## Dark Matter, Double Supernova Neutrino Explosion, Degenerate Vacua, Pre-determination ? Why Standard Model Group ?

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.

## Quantum Field Theory for Gravity

Much of the community has been exploring exotic solutions for the UV completion of gravity. I am interested in exploring a different possibility, that of an asymptotically free quantum field theory. There are obstacles of course, and the talk will be a discussion of the problems and a possible pathway through them.

## 6th Rome Joint Workshop: Weird Theoretical Ideas

Aim of the workshop: In spite of its consolidated experimental success, the Standard Model of particle physics falls short of describing all observed phenomena. Elegant and well motivated theoretical ideas, such as Supersymmetry, Technicolor or Grand Unification, have so far found no support from experimental results. The longed-for discovery of some kind of physics beyond the Standard Model, that could guide us to replace these ideas with new theoretical paradigms, has so far escaped all experimental efforts. Given this situation, any serious attempt to approach the incompleteness of the Standard Model from originally different and unconventional perspectives should receive proper consideration. Fearless exploration outside the box might provide more insights than lengthy struggles through standard thinking. During this 3-day workshop we plan to review some recent attempts to approach fundamental physics issues from non standard perspectives. We plan to have only two or three talks each day and plenty of time to analyze jointly the good and bad of the various proposals, confront ideas and discuss. Scientific Program and Speakers: John Donoghue (Massachusetts U., Amherst) “Quantum Field Theory for Gravity” Gia Dvali  (LMU, ASC & MPI, Munich & NYU, CCPP, New York)  “Classicalization” Renate Loll (Radboud U., NL) “Quantum Gravity, or: Give me (more) observables!”  Matthew McCullough  (CERN) “Hyperbolic Higgs, Clockwork and Relaxion” Holger F.B.
