Is the Higgs boson the inflaton?

The Higgs boson mass miraculously turns out to have a value very close to what has been expected form vacuum stability of the Standard Model up to the Planck scale. This opens the possibility that the Higgs boson not only provides masses to all SM particles, but very likely also supplied a huge dark energy which inflated the young universe just after the Big Bang. The Higgs boson looks to be a natural candidate for the inflaton. Higgs decays are reheating the universe after inflation. I also emphasize the role of the hierarchy problem and the cosmological constant problem

CYGNUS-TPC kick-off meeting: a mini-workshop on directional Dark Matter searches and coherent neutrino scattering

The aim of this mini-workshop is to discuss the recent status of Dark Matter searches and coherent neutrino scattering, with a stress on innovative technologies with low background, low energy threshold and directional capability. In this context, we are presenting a new international enterprise for the construction of a global galactic elastic recoil Observatory, to be called CYGNUS-TPC. We envisage the ultimate vision of this experiment to be a multi-ton target mass gas to be detected by Time Projection Chambers distributed in five underground laboratories scattered around the globe. We are currently building a new international collaboration to prepare a Letter Of Intent and a proposal. For these reasons, the first day of the workshop will be dedicated to phenomenological and experimental reviews, together with CYGNUS-TPC presentation, while the second to a more detailed discussion of CYGNUS-TPC LOI and collaboration formulation.

A discussion on the 750 GeV di-photon anomaly

The recent analyses from ATLAS and CMS showed an anomalous excess of events in di-photon searches at an invariant mass of about 750 GeV. Even if more data are required to clarify the origin of these excesses, after reviewing the experimental results, I will give a brief overview of the possibile theoretical interpretations of this anomaly.

Physics Beyond the Standard Model

New physics beyond the highly successful Standard Model is strongly motivated by a number of experimental observations in particle physics & cosmology. We explore the predictions of well-motivated models especially supersymmetric ones. The recently reported diphoton excess by ATLAS. & CMS experiments will be briefly discussed.

The role of alpha_{QED}(M_Z) at future e+e- colliders and prospects to improve its accuracy with low energy e+e- collider data

“Physics behind precision'' at future linear or circular colliders (ILC /FCC projects) require imporved input parameters. I will review the role alpha_{QED, eff} at future collider energies and report on possible progres from low energy machines. Besides "what physics can be discovered" with such FCC-ee option, we also would like to understand better how nature works when energies increase.

Measurement of hadronic cross-sections with CMD-3 at VEPP-2000

The first round of data taking with CMD-3 detector at VEPP-2000 e+e collider (BINP, Novosibirsk, Russia) was performed in 2011-2013. The CMD-3 is the general purpose particle detector, equipped by tracking system, two crystal (CSI and BGO) calorimeters, liquid Xe calorimeter, TOF and muon systems. The main goal of experiments at CMD-3 is the measurement of cross-sections and dynamics of exclusive modes of e+e- —> hadrons. In particular, these results provide important input for calculation of the hadronic contribution to the muons anomalous magnetic moment. Here we present the survey of results of analysis of data taken in 2011-2013, including modes of e+e- —> hadrons with up to 6 pions or 2 kaons in final state. About 60 1/pb were taken in the energy range from 0.32 to 2.0 GeV in c.m. The beam energy was continuously measured concurrently with the data taking using Compton backscattering. In 2016 VEPP-2000 resumed operations after upgrade with project luminosity of 1032cm2s-1 at 2 GeV.

Charged Particle Therapy and Nuclear Physics

The use of charged particles and nuclei in cancer therapy (hadrontherapy) is one of the most successful cases of application of nuclear physics to medicine. The physical advantages in terms of precision and selectivity, combined with the biological properties of densely ionizing radiation, make the charged particle approach an elective choice in a number of cases. Hadrontherapy is in continuous development and it is an interdisciplinary field where physicians, biologists and physicists contribute together. Indeed the role of physicists is still very important for the progress of Particle Therapy, and the purpose of this seminar is mainly to discuss those aspects where nuclear and particle physicists are presently active. A particular attention will be devoted to the problem of reducing the uncertainties on particle range. This problem is closely connected with the ability to achieve the promised precision. At present, uncertainties in particle range lead to the employment of safety margins, at the expenses of treatment quality. One of the research items in particle therapy is therefore aimed at developing methods to verify the particle range in patients. Non-invasive in-vivo monitoring of the particle range can be performed by detecting secondary radiation, emitted from the patient as a result of nuclear interactions of charged hadrons with tissue, including β+ emitters, prompt photons, and charged particles. Dedicated detector systems are being developed. The proposed approaches require reliable and precise Monte Carlo predictions and a dedicated research activity for the continuous improvement of existing models is also necessary.

LNF Mini-Workshop Series: The Detection of Gravitational Waves, toward a new era in astrophysics research

After 100 years from the formulation of the theory of general relativity by Albert Einstein, gravitational waves have been finally observed on September 14, 2015 as a transient signal by the two detectors of the Laser Interferometer Gravitational-Wave Observatory, LIGO. In this mini-workshop the results by LIGO and VIRGO collaborations will be presented, together with a historical review of gravitational wave detectors. Future implications of gravitational waves observation in astrophysics will be also discussed.
