Measurement of $^{12}$C Fragmentation Cross Sections on C, O, and H in the Energy Range of Interest for Particle Therapy Applications
/ Mattei, I ; Alexandrov, A ; Alunni Solestizi, L ; Ambrosi, G ; Argiro, S ; Bartosik, N ; Battistoni, G ; Belcari, N ; Biondi, S ; Bisogni, M G et al.
In a carbon ion treatment the nuclear fragmentation of both target and beam projectiles impacts on the dose released on the tumor and on the surrounding healthy tissues. Carbon ion fragmentation occurring inside the patient body has to be studied in order to take into account this contribution. [...]

Search for Darkonium in $e^+e^-$ Collisions
/ BABAR Collaboration
Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. [...]

In hadron therapy, the accelerated ions, interacting with the body of the patient, cause the fragmentation of both projectile and target nuclei. The fragments interact with the human tissues depositing energy both in the entrance channel and in the volume surrounding the tumor. [...]

The FOOT FragmentatiOn Of Target Experiment

In proton-therapy clinical practice a constant RBE equal to 1.1 is adopted, regardless of the demonstrated RBE variations, which depends on physical and biological parameters. Among other mechanisms, nuclear interactions might influence the proton-RBE due to secondary heavier particles produced by target fragmentation that can significantly contribute to the total dose: an un-wanted and undetermined increase of normal tissues complications probability may occur.

Particle Therapy (PT) is an emerging technique, which makes use of charged particles to efficiently cure different kinds of solid tumors. The high precision in the hadrons dose deposition requires an accurate monitoring to prevent the risk of under-dosage of the cancer region or of over-dosage of healthy tissues. [...]

Measurement of charged particle yields from PMMA irradiated by a 220 MeV/u12Cbeam

Rome La Sapienza (main)) et al.
The radiation used in hadrontherapy treatments interacts with the patient body producing secondary particles, either neutral or charged, that can be used for dose and Bragg peak monitoring and to provide a fast feedback on the treatment plans. Recent results obtained from the authors on simplified setups (mono-energetic primary beams interacting with homogeneous tissue like target) have already indicated the correlation that exists between the flux of these secondaries coming from the target (e.g. [...]

Low Energy Nuclear Reactions?
/ Polosa, A.D. (speaker) (Dip. Fisica, Sapienza Universita di Roma) ; Faccini, R. (speaker) (Dip. Fisica, Sapienza Universita di Roma)
After an introduction to the controversial problem of Low Energy Nuclear Reactions (LENR) catalyzed by neutrons on metallic hydride surfaces we present the results of an experiment, made in collaboration with ENEA Labs in Frascati, to search neutrons from plasma discharges in electrolytic cells.
The negative outcome of our experiment goes in the direction of ruling out those theoretical models expecting LENR to occur in condensed matter systems under specific conditions.
Our criticism on the theoretical foundations of such models will also be presented.

Monitoring the dose delivered during proton and carbon ion therapy is still a matter of research. Among the possible solutions, several exploit the measurement of the single photon emission from nuclear decays induced by the irradiation. [...]
