Open Charm Reconstruction in ALICE Experiment at LHC
Abstract
Open Charm mesons produced in relativistic nuclear reactions are among themost direct probes to investigate the medium produced in these collisions. It isimportant to measure the production of as many charmed hadrons as possible,such as D0, D+, Ds, D and c. The measurement of their relative yield canprovide information on the hadronization mechanism and is necessary to reducethe systematic error on total charm cross-section. The ALICE experiment at theLHC is designed to perform such measurements at mid-rapidity by means of itsbarrel tracking detectors. The study on exclusive reconstruction of the D0, Ds,and D+ mesons through their hadronic decay channels will be presented for p+pcollisions at 7 TeV. The first results on D-meson spectra and the D+/D0 ratio willalso be shown.1
Energy Storage R&D: From Fundamental Science to Application
Abstract
In this talk I shall give a general overview of the current state-of-theart research directions in the area of energy storage science andtechnology. Specific examples would be demonstrated in the area ofLithium-ion batteries and energy storage materials that can potentiallyrevolutionize the personal mobility and transportation sector. Thesedevelopments would lead to a sustainable “all electric†based technologythat could potentially eliminate the use of green house emitting fossilbased fuels. I shall provide a brief overview of various charge storingmechanism ranging from intercalation based transition metal oxidecompounds to conversion based reactions that can provide higher specificenergy and power density.The second part of the talk will focus on some of the research effortundertaken in my group including carbon fiber based batteries, high energydensity Li-ion electrode materials and their characterization.Fundamentals of Lithium atom transport and imaging using Neutron, scanningtransmission electron microscopy (STEM) and confocal micro-Ramanspectroscopy will be presented.
