San Raffaele) ; Camera, F (Milan U. ; INFN, Milan ; LASA, Segrate) ; Canella, F (Milan U.) et al.
The need of a fs-scale pulsed, high repetition rate, X-ray source for time-resolved fine analysis of matter (spectroscopy and photon scattering) in the linear response regime is addressed by the conceptual design of a facility called MariX (Multi-disciplinary Advanced Research Infrastructure for the generation and application of X-rays) outperforming current X-ray sources for the declared scope. MariX is based on the original design of a two-pass two-way superconducting linear electron accelerator, equipped with an arc compressor, to be operated in CW mode (1 MHz). [...]

Theory pipeline for PDF fitting
/ Barontini, Andrea (Milan U. ; INFN, Milan) ; Candido, Alessandro (Milan U. ; INFN, Milan) ; Cruz-Martinez, Juan (Milan U. ; INFN, Milan ; CERN) ; Hekhorn, Felix (Milan U. ; INFN, Milan) ; Schwan, Christopher (Wurzburg U.) ; Magni, Giacomo (Vrije U., Amsterdam)
Fitting PDFs requires the integration of a broad range of datasets, both from data and theory side, into a unique framework. While for data the integration mainly consists in the standardization of the data format, for the theory predictions there are multiple ingredients involved. [...]

AEgIS Experiment: Status & Outlook
/ Lansonneur, P (Lyon, IPN) ; Aghion, S (Milan, Polytech. ; INFN, Milan) ; Amsler, C (Stefan Meyer Inst. Subatomare Phys.) ; Bonomi, G (U. Brescia ; INFN, Pavia) ; Brusa, R S (Trento U. ; TIFPA-INFN, Trento) ; Caccia, M (INFN, Milan ; Insubria U., Como) ; Caravita, R (Genoa U. ; INFN, Genoa) ; Castelli, F (INFN, Milan ; Milan U.) ; Cerchiari, G (Heidelberg, Max Planck Inst.) ; Comparat, D (LAC, Orsay) et al.
The AEGIS experiment 1 (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is planned to perform the first measurement of the gravitational acceleration on antimatter by observing the free fall of antihydrogen atoms. By combining techniques based on recent developments in the production of positronium and its laser excitation to Rydberg states, such a study seems indeed to be feasible for neutral antimatter.

Testing ab initio nuclear structure in neutron-rich nuclei: lifetime measurements of second 2$^+$ states in $^{16}$C and $^{20}$O
/ Ciemala, M. (Cracow, INP) ; Ziliani, S. (Milan U. ; INFN, Milan) ; Crespi, F.C.L. (Milan U. ; INFN, Milan) ; Leoni, S. (Milan U. ; INFN, Milan) ; Fornal, B. (Cracow, INP) ; Maj, A. (Cracow, INP) ; Bednarczyk, P. (Cracow, INP) ; Benzoni, G. (INFN, Milan) ; Bracco, A. (Milan U. ; INFN, Milan) ; Boiano, C. (INFN, Milan) et al.
To test the predictive power of ab initio nuclear structure theory, the lifetime of the second 2+ state in neutron-rich 20O, tau(2+_2 ) = 150(+80-30) fs, and an estimate for the lifetime of the second 2+ state in 16C have been obtained, for the first time. The results were achieved via a novel Monte Carlo technique that allowed us to measure nuclear state lifetimes in the tens-to-hundreds femtoseconds range, by analyzing the Doppler-shifted gamma-transition line shapes of products of low-energy transfer and deep-inelastic processes in the reaction 18O (7.0 MeV/u) + 181Ta.

Gravity and antimatter: the AEgIS experiment at CERN

From the experimental point of view, very little is known about the gravitational interaction between matter and antimatter. In particular, the Weak Equivalence Principle, which is of paramount importance for the General Relativity, has not yet been directly probed with antimatter. [...]
