Proton therapy, a cutting-edge cancer treatment, is currently employed successfully for treating deep-seated tumors near vital organs. However, uncertainties surrounding the Relative Biological Effectiveness (RBE) of proton beams pose limits to its efficacy. A significant factor contributing to these uncertainties is the production of highly-ionizing, short-ranged secondary fragments through...
We investigate the multiplicity fluctuations of charged particles observed in high-energy nuclear collisions and relate them to the size of hadronizing systems which happen during such processes. We use the average multiplicities N and variances Var (N) of multiplicity distributions of charged particles produced in centrality selected collisions of relativistic heavy-ion nuclei to evaluate the...
Lattice simulation of QCD at small net baryon densities and high temperature have revealed that the transition to hadronic phase to the deconfined quark-gluon plasma is a crossover. Recently, the structure of neutron stars have been studied with a crossover equation of state by means of a switching function to model a smooth transition from a pure neutron matter to massless quarks [1]. The...
A detailed study on the sensitivity of the production channel of two Z bosons in association with two jets (ZZjj) at the High-Luminosity Large Hadron Collider (HL-LHC) and future colliders, such as the Future Circular Collider (FCC), is presented, focusing on the Quartic Gauge Couplings (QGCs) within the framework of an Effective Field Theory (EFT) with dimension-eight operators. Using Monte...
We investigate the formation mechanisms and cosmological implications of Primordial Black Holes (PBHs) within the framework of superfluid dark matter (SFDM), integrating quantum field theory with numerical simulations and gravitational wave predictions. Our theoretical framework, rooted in complex scalar fields $\phi_1$ and $\phi_2$, includes self-interactions and vortex dynamics, predicting a...
