f0(980) resonance production in pp collisions with the ALICE detector at the LHC
Abstract
We report on a preliminary study of the production of f(0)(980) ->
pi(+)pi(-) at mid-rapidity (vertical bar y vertical bar < 0.5) performed
with the ALICE detector at the LHC in minimum bias pp collisions at the
centre-of-mass energy root s = 5.02 TeV. The f(0)(980) signal extraction
is challenging due to the large background from correlated pi(+)pi(-)
pairs from other resonance decays in the invariant mass window under
study, as well as due to the combinatorics from uncorrelated pairs. We
present the strategy for the signal extraction and first results in
terms of p(T)-dependent production yields. The results are discussed and
compared with production yields of other resonances and stable hadrons.
