The NUMEN project @ LNS: Status and perspectives

2017

The NUMEN project aims at accessing experimentally driven information on Nuclear Matrix Elements (NME) involved in the half-life of the neutrinoless double beta decay (0νββ), by high-accuracy measurements of Heavy Ion (HI) induced Double Charge Exchange (DCE) reaction cross sections. In particular, the (18O,18Ne) and (20Ne,20O) reactions are used as tools for β+β+ and β−β− decays, respectively. In the experiments, performed at INFN - Laboratory Nazionali del Sud (LNS) in Catania, the beams are accelerated by the Superconducting Cyclotron (CS) and the reaction ejectiles are detected the MAGNEX magnetic spectrometer. The measured cross sections are challengingly low (a few nb), being the tota…

Electron spectra in forbidden β decays and the quenching of the weak axial-vector coupling constant gA

2017

Evolution of the electron spectra with the effective value of the weak axial-vector coupling constant gA was followed for 26 first-, second-, third-, fourth- and fifth-forbidden β− decays of odd-A nuclei by calculating the involved nuclear matrix elements (NMEs) in the framework of the microscopic quasiparticle-phonon model (MQPM). The next-to-leading-order terms were included in the β-decay shape factor of the electron spectra. The spectrum shapes of third- and fourth-forbidden nonunique decays were found to depend strongly on the value of gA, while first- and second-forbidden decays were mostly unaffected by the tuning of gA. The gA-driven evolution of the normalized β spectra was found t…

Identificación de TCRs reactivos contra neoantígenos tumorales en muestras de pacientes con CPNM mediante secuenciación de nueva generación. Implicac…

2021

A pesar del éxito de la inmunoterapia con los bloqueantes de los puntos del control inmune (ICBs) en el cáncer de pulmón, el porcentaje de pacientes que se beneficia de este tipo de tratamiento sigue siendo inferior al 30%, por lo que aún es necesario el desarrollo de nuevos posibles biomarcadores para una mejor selección de los pacientes. El objetivo principal del presente trabajo de tesis doctoral es caracterizar el repertorio de la cadena beta del receptor de células T (TCR-β) en sangre periférica y correlacionar con las variables demográficas, clínico-patológicas, predictivas y pronósticas en una cohorte de pacientes con cáncer de pulmón no microcítico (CPNM) en estadios avanzados trata…
