The High Energy, Cosmology and Astroparticle Physics (HECAP) section at ICTP is studying some of the most exciting areas in physics today, from string theory to physics at large energy colliders, from neutrino phenomenology to alternative cosmologies.
HECAP collaborates closely with the staff of the International School for Advanced Studies (SISSA), the Department of Theoretical Physics of Trieste University, and with the physicists of the Trieste section of the Italian National Institute of Nuclear Physics (INFN).

BV-BRST deformation formalism and gaugings of supergravity
Abstract. Due to the electric-magnetic duality of supergravity, one is able to have a Lagrangian description of the theory in different duality frames. Although the gaugings of supergravity have been classified as long as we stick to the electric frame, it is not for long that the similar analysis in an arbitrary electric-magnetic duality frame has been done. After a review of the topic and BV deformation formalism, we will go on to show a no-go theorem for the gaugings of N=4 and maximal supergravity in four dimensions.

Galactic Rotation Curves vs. Ultra-Light Dark Matter
Abstract. Bosonic ultra-light dark matter (ULDM) would form cored density distributions at the center of galaxies. These cores, seen in numerical simulations, admit analytic description as the lowest energy bound state solution ("soliton") of the Schroedinger-Poisson equations. Numerical simulations of ULDM galactic halos found an empirical scaling relation between the mass of the large-scale host halo and the mass of the central soliton. We show that this relation predicts that the peak circular velocity, measured for the host halo in the outskirts of the galaxy, should approximately repeat itself in the central region. Contrasting this prediction to the measured rotation curves of well-resolved near-by galaxies, we show that ULDM in the mass range m ~ (10-22 - 10-21) eV, which has been invoked as a possible solution to the small-scale puzzles of CDM, is in tension with the data.

1st Joint ICTP-Trieste/ICTP-SAIFR School on Particle Physics | (smr 3220)
In 2018, Run II of the LHC will be well under way, and it will be important to assess what has been learned, as well as to discuss the directions in which the field might move in the near-term and medium-term future. The school will therefore be largely focused on LHC Physics, but without forgetting other areas that can give complementary information regarding the nature of the physics at the TeV scale.
Following the tradition of the Summer Schools on Particle Physics at the ICTP in Trieste, the school aims at giving a detailed overview of particle physics, and covering important areas where recent progress has been made in the field. We will have at most three lectures per day, giving ample time for discussion and problem solving by the students. We will also encourage students to give short presentations on their research.
There is no registration fee and limited funds are available for travel and local expenses.

» Conference on Shedding Light on the Dark Universe with Extremely Large Telescopes | (smr 3218)
The HECAP section has research and visitors' programmes mostly aimed at scientists from developing countries.
The main motivation to study string theory is because it promises to provide a framework to unify all matter and interactions, including gravity, in a consistent theory. Despite the intrinsic difficulty of dealing with a theory that manifests itself at scales as high as the Planck mass, for more than 25 years there has been continuous progress in order to connect string theory and low-energy physics. This refers to extensions of the Standard Model of particle physics and cosmology that could lead to some observable implications.
