Research Activities in ALICE |

My main research interest as a member of the
ALICE collaboration was on the study of the QGP using open-charm probes. I started to work on D mesons analysis for
my master thesis, studying simulations of the elliptic flow
of charmed particles produced in the Quark Gluon Plasma
generated in Pb-Pb collisions at LHC energies. Part of
this work has been published on Phys Rev. C.
The work on elliptic flow in QGP continued with profesor
Kodama at Universidade Federal do Rio de Janeiro (an
article on this was submitted to Phys Rev. G).
My PhD thesis project was on D+ meson analysis at the LHC
with ALICE.
I followed the D+ meson
analysis through their hadronic decay channel at
the ALICE experiment inside the D2H working group.
To do this I studied the D+ meson production cross
section in proton-proton collision delivered by
the LHC at the energies of √s=7 TeV and √s=2.76
TeV. With other D2H and ALICE collaborators we
used These studies as baseline to perform the
measurement of the D meson nuclear modification
factor RAA in
Pb-Pb collisions at √s(NN)=2.76 TeV order to
estimate the energy loss of charm quarks in the
medium. Futhermore, another indication on how
charm propagate through the medium can be obtained
from the D+ meson elliptic flow measurement, on
which I'm also working at the moment.
I am currently member of 2 paper preparation
groups inside the ALICE collaboration with the
goal to present the results on D meson RAA
and elliptic flow to JHEP and PRC journals.
Further details on these analyses can be found
following the
PhD and

I serve as expert-on-call for
the ALICE-SDD detector. The SDD is part of the ALICE Inner
Tracking System (ITS) and contributes to the excellent
ALICE tracking and vertexing capabilities. It can also
provide charged particle identification at low momentum
through particles energy loss inside the drift. The system
is sensitive to very small changes in temperature,
humidity and other experimental conditions. As expert on
call I worked on maintaining the system efficient
and well calibrated, and I studied its performances over
time.

| The elliptic flow is an asymmetry
in the final particle momentum distribution driven by spatial
anisotropies in the primary collision. It is considered as one
of the main signatures of the presence of QGP and its study can
help to characterize some of the medium properties (such as EoS
and initial conditions). Besides my work on charm elliptic flow
at ALICE, I also worked on the introduction of flow in
MonteCarlo generators (published in PRC) and on the possible
presence of elliptic flow in high multiplicity proton-proton
collisions. This latest work was prepared while visiting at
Universidade Federal do Rio de Janeiro. |
