This meeting continues the series of workshops on the Cylindrical GEM detectors, held in the Frascati Laboratory of INFN. We are indebted to INFN, IHEP, USTC and MAECI (the Italian Ministry for Foreign Affairs and International Cooperation) for jointly contributing funding to this meeting, in the cadre of the 3-year Program of Great Relevance PGR00136, Italy-China 2013-2015.

Recently astronomical data are accumulated, reporting discoveries of very early formed objects, such as supermassiveblack holes (quasars), gamma bursters, supernovae, and very bright galaxies at high redshifts. Moreover, there is an evidence to existence of starts in our Galaxy which are too old, even older than the universe. All such objects cannot be created in the frameworks of accepted scenarios of their formation. An origin of supermassive black holes observed in the centers of many (maybe all) large and some small galaxies also remains mysterious. After a review of the observations a model is presented that can explain the unusual features of the data. The model is based on a slightly modified scenario of baryogenesis motivated by supersymmetry. As a byproduct the model can predict abundant cosmological antimatter, in particular almost at hand, in the Galaxy. Though the model may be rather speculative, the observed objects present serious challenge to the theory and possibly indicate that “there is something rotten in the state of the universe”

Precision is the new frontier of LHC phenomenology. Accurate theoretical predictions are essential for exploiting the full potential of the machine. I will discuss the role of all-order resummations in providing high-precision predictions for a number of observables at the LHC. I will cover different resummations in QCD, such as soft resummation, collinear resummation and high-energy resummation, and discuss alternative resummation techniques. I will finally present implications of improved theoretical predictions on New Physics searches.

A significant progress has been made in controlling the properties of the radiation emitted by a FEL amplifier. Experiments have demonstrated both the possibility to increase the temporal coherence and to reduce the amplifier length to reach saturation, by seeding it with an external source. The FERMI seeded Free Electron Laser (FEL) is based on two complementary FEL lines, FEL-1 and FEL-2. FEL-1 is a single stage cascaded FEL delivering light in the 65-20nm wavelength range, while FEL-2 is a double stage cascaded FEL where the additional stage extends the frequency up-conversion to the spectral range of 20-4nm. The main aspects and results achieved with these two beam lines will be briefly reviewed, together with the future possibilities opened by the increased control on the FEL process allowed by the interaction with the external seed.

The workshop on Muon Identification at LHCb will be held at the Frascati National Laboratory of INFN, in the B. Touschek Auditorium. The meeting will focus on the ongoing developments for maximising the performances on the Muon Identification, in the present phase and for LHCb upgrade. The goal is to gather consolidated experiences and new ideas from  detector, trigger and software experts and to create a forum of discussion where to address the main challenges and the best solutions for the future.

The nature of dark matter (DM) is one of the most puzzling open problems of cosmology and particle physics. Succesfull structure formation requires the thermal velocity of the DM particles to be small, i.e., the DM to be “cold” or “warm”, albeit a subdominant “hot” component could be present. Several candidates for the role of dark matter have been proposed: among them sterile neutrinos, axions (and axion-like particles) and majorons. These candidates could costitute the dominant cold/warm DM or provide a small hot component, in different regions of the respective parameter spaces. In my talk I will review present constraints on these candidates, also in light of the recent observations of the Planck satellite.

The conference in 2015 is devoted to recent developments in nanoscience and its manifold technological applications. It consists of a number of tutorial/keynote lectures, as well as research talks presenting frontier nanoscience research developments and innovative nanotechnologies in the areas of biology, medicine, aerospace, optoelectronics, energy, materials and characterizations, low-dimensional nanostructures and devices.

In this proposal we aim at hunting for New Physics in the largely unexplored domain of Dark Sectors made of very weakly interacting particles with masses well below the electroweak scale and henceforth inaccessible to the LHC experiments.
