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...

Now that gravitational waves from compact binary coalescences have been successfully detected by the global LIGO-Virgo network, a key challenge is to improve the detector sensitivity in order to detect more transient sources — weaker or located further away. The detectors' sensitivity can be enhanced by increasing the laser power travelling within the arm cavities, for it reduces the effect of...

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...

Progress of the Picosec Micromegas concept towards a particle detector with a restive and segmented readout Detectors with a time resolution of several 10 ps and robustness under higher particles flux are necessary for a accurate vertex separation in future HEP experiments. The Picosec detector concept is a Micro-Pattern Gaseous Detector (MPGD) based solution facing this particular problem....

The shape of a nucleus is one of its fundamental properties. The nuclei in the neutron-rich region around mass 100 are well known to exhibit rapid shape changes. The simplest estimate of nuclear deformation in even-even nuclei can be obtained from the energy of the 2+1 state. For Sr (Z = 38) and Zr (Z = 40) isotopes this energy is observed to decrease dramatically at N = 60, while its...

Low temperature nuclear orientation (LTNO) allows to study polarized exotic nuclei. At very low temperature (~10mK) nuclei can experience a very high polarization in the hyperfine field which exists into a ferromagnetic metal host. The decay products can be observed using proton, alpha or beta-particle detectors fitted within the cryostat and/or external gamma or neutron detectors, providing a...

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...

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...

Hadron therapy is an innovative type of radiotherapy for cancer treatment which enables tumour cells to be more effectively destroyed than conventional radiotherapy using photons. The precise knowledge of the lineal energy of particles is used in the field of microdosimetryas a fundamental parameter in the prediction of the relative biological efficiency (RBE) of clinical beams.The access to...

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...

At ATLAS experiment, this analysis is using inclusive high pT Z boson events which decay into two lepton final state to search for deviations from SM expectations with Run2 data. The leptonic decays of the Z bosons at high pT provide a clean and fully triggered data sample. The requirement of the high pT Z bosons also helps to suppress the SM background contribution, especially the QCD...
