OBJECTIVES OF WP
27

(FROM ANNEX I)

P
ROGRESS MADE DURING THE
REPORTING PERIOD

In the ALICE spectrometer, in order to
expand the physics capabilities of EMCal
by enabling back
-
to
-
back correlation
measurements, a large acceptance
Electromagnetic Calorimeter positioned
opposite to and down EMCa
l (DCal) is
under study.



Thus the aim of the proposed JRA is to
perform an extensive study of jet
quenching in heavy ion collisions by:


• a combination of inclusive and correlation
measurements enabled by large acceptance
Electromagnetic Calorimeters
EMCal and
DCal;


• a synergy of technological and conceptual
innovations for jet trigger and jet
reconstruction;


• a new theoretical formalism and Monte

Carlo modelization for the jet quenching.
