phenomenology group at the University of Florence is interested in
several aspects of the phenomenology of elementary particles in
the Standard Model and Beyond. The LHC experiment is presently
shedding light on the next energy frontier in physics, 10^12 eV.
This requires precise theoretical computations to extract
from the experiment. The main goal will then be to determine the
nature of electro-weak symmetry breaking in the SM and uncover the
physics associated to the Higgs boson.
Beyond the Standard Model (Casalbuoni, De Curtis, Dominici, Panico, Redi, Redigolo, Tesi):
Standard Model is arguably the most successful theory to date
describing all we know about elementary particles and their
interactions. The recent discovery of the Higgs boson at the LHC,
completing the degrees of freedom of the SM predicted long ago, has
been the last big triumph. Despite these successes the SM is known to
be incomplete for theoretical and phenomenological reasons and new
degrees of freedom must exist. LHC has in this regard the best chances
to find new physics due to the naturalness problem in the SM that
hints to new dynamics at the TeV scale.
group is broadly interested in all the physics beyond the SM that is
necessary to address the many shortcomings of the SM.
main present interests are:
physics: composite Higgs models, new approaches to
the hierarchy problem, new strong dynamics.
physics: experimental signatures of composite Higgs models, top
partners, vector resonances.
physics beyond the SM
Matter: WIMPS and axions
Dynamics and supersymmetry
QCD and Particle Physics Phenomenology at
High Energies(Catani, Ciafaloni, Colferai
activity aims at improving the understanding of strong interactions at
short distances (in regimes of high energies and large
transferred momenta) and at providing accurate theoretical predictions
for particle physics phenomenology (within and beyond the
Standard Model) at high-energy accelerators. The group has a wide
expertise on both theoretical and phenomenological aspects.
Topics of current interest include:
for the computations of QCD radiative corrections at the
next-to-leading order (NLO) and the next-to-next-to-leading order
physics for hard-scattering processes in hadron collisions and at
the LHC (production of Higgs bosons, vector
bosons, high-$p_t$ jets and photons, heavy quarks, supersymmetric
physics in DIS and high-energy QCD factorization of heavy-quarks
and jet production in DIS and hadron-hadron collisions
infrared (soft and collinear) structure of
multiparticle scattering amplitudes in gauge theories and
factorization issues in QCD
developments and phenomenological applications of all-order QCD
resummations of logarithmically-enhanced radiative corrections
