The D2I2 association (which stands for Doctorants et Docteurs des deux Infinis) is a social and professional network for PhD students and doctors in high energy physics of the two infinites. From parties to seminars you can meet new people, create your own network and use it to find a postdoc or a job after your PhD.
The expected increase of the particle flux at the high luminosity phase of the LHC with instantaneous luminosities up to L=7.5$\times$10$^{34}$ cm$^{-2}$s$^{-1}$ will have a severe impact on pile-up. The pile-up is expected to increase on average to 200 interactions per bunch crossing. The performance of particle reconstruction will be severely degraded in the end-cap and forward region of the...
The PandaX-III experiment aims to search for the rare neutrinoless double beta decay in Xenon 136. To achieve this goal, it is mandatory to select carefully the main detectors that have to achieve a very good energy resolution (at the level of 1% at 2.5MeV) and a good spatial resolution for the discrimination between double beta events and external gammas coming from radioactive isotopes. It...
Neutrinoless double-beta decay is a hypothetical rare nuclear transition (T1/2>1026 yr) and its observation would imply lepton number violation and Majorana nature of neutrinos (ν ̅=ν), allowing to determine the absolute scale of the neutrino mass and to probe effects beyond the Standard Model. In this transition two neutrons decay simultaneously into two protons and two electrons and it is...
At very high energy densities, matter undergoes a phase transition from confined states called hadrons to a soup of their constituents, called the quark gluon plasma. The QGP can be artificially produced in heavy ion collisions. It is studied using different probes, one of which is charmonium states. The talk will show results from the CMS collaboration at CERN regarding charmonium production...
Generalized Parton Distributions (GPDs) describe the correlations between the longitudinal
momentum and the transverse position of the partons inside the nucleon. They give access to the
contribution of the orbital momentum of the quarks to the nucleon spin. They are nowadays the
subject of an intense effort of research, in the perspective of understanding nucleon structure. GPDs
have been...
ALICE experiment at LHC studies through ultra-relativistic heavy ion collisions, a deconfined state of matter, the Quark Gluon Plasma (QGP). This state raises many questions about mechanisms of strong interaction and the cohesion of matter. Moreover, QGP is an extremely hot and dense state that behaves more like a nearly ideal, strongly interacting fluid and it can represents the universe at...
Despite remarkable advancements, the tolerance dose of normal tissue continues being the main limitation in radiotherapy. To overcome it, we have recently proposed a novel concept: proton minibeam radiation therapy (pMBRT). It combines the inherent physical advantages of protons with the normal tissue preservation observed when irradiating with submillimetric, spatially fractionated beams...
My thesis work focuses on taking advantage of the newer analysis and selection techniques to search for tau leptons coming from Higgs which was produced associated to two tops (ttH) in the CMS detector. The ttH production mode is important to characterize the properties of the Higgs boson and in particular its coupling to top quarks, to which the ttH process has direct access. Given the mass...
