On the Chinese Exchange Rate Regime: an Attempt to Flexibility during 2015
This study will demonstrate, through an econometric and asset allocation approach, if and
how the Chinese exchange rate regime was changing during 2015. Particularly, China to improve its
exchange rate formation system implemented, during July and August 2015, three depreciation as a
step toward a market-oriented exchange rate. This situation, along with the new right of the RMB to
be an international currency in SDR should generate a loss of weight about the USD in the Chinese
basket peg. For this reason, moving from Frankel-Wei’s basic econometric model - but with some
appropriate changes - our objective is to verify if the Chinese monetary policy about the exchange
rate has affected the inner balance of the Chinese basket-peg leading it towards a flexible exchange
rate regime
Looking for anomalous gamma-gamma-H and Z-gamma-H couplings at future linear collider
We consider the possibility of studying anomalous contributions to the
gamma-gamma-H and Z-gamma-H vertices through the process e-gamma--> e-H at
future e-gamma linear colliders, with Sqrt(S)=500-1500 GeV. We make a model
independent analysis based on SU(2)xU(1) invariant effective operators of dim=6
added to the standard model lagrangian. We consider a light Higgs boson (mostly
decaying in bar(b)-b pairs), and include all the relevant backgrounds. Initial
e-beam polarization effects are also analyzed. We find that the process
e-gamma--> e-H provides an excellent opportunity to strongly constrain both the
CP-even and the CP-odd anomalous contributions to the gamma-gamma-H and
Z-gamma-H vertices.Comment: LaTeX, 33 pages, 16 eps figures, extended section
Measuring the SUSY Breaking Scale at the LHC in the Slepton NLSP Scenario of GMSB Models
We report a study on the measurement of the SUSY breaking scale sqrt(F) in
the framework of gauge-mediated supersymmetry breaking (GMSB) models at the
LHC. The work is focused on the GMSB scenario where a stau is the
next-to-lightest SUSY particle (NLSP) and decays into a gravitino with lifetime
c*tau_NLSP in the range 0.5 m to 1 km. We study the identification of
long-lived sleptons using the momentum and time of flight measurements in the
muon chambers of the ATLAS experiment. A realistic evaluation of the
statistical and systematic uncertainties on the measurement of the slepton mass
and lifetime is performed, based on a detailed simulation of the detector
response. Accessible range and precision on sqrt(F) achievable with a counting
method are assessed. Many features of our analysis can be extended to the study
of different theoretical frameworks with similar signatures at the LHC.Comment: 28 pages, 12 figures (18 eps files). Revised version v2(published in

Geometria e progetto. Ipotesi di riuso per il palazzo Vernazza a Castri
Dall’Antichità al Rinascimento, da Pitagora a Keplero, aritmetica, geometria, musica e astronomia hanno indagato il numero, lo spazio, il suono e il movimento dei corpi celesti. Queste quattro discipline venivano già pensate e insegnate da Platone come un insieme unitario, che fondeva lo studio degli oggetti matematici con l’aspirazione filosofica al vero, al bello e al bene. Il Quadrivium viene reinterpretato in questo lavoro e l’edificio diviene testimone, testo parlante, memoria scritta in molti linguaggi e restituisce al lettore di oggi un patrimonio un tempo riservato a pochi. Il Palazzo Vernazza di Castri di Lecce è studiato in questa sperimentazione progettuale a partire dalla riscoperta della sua misura storica, con il contributo delle moderne tecniche di rilievo che hanno supportato questi studi, allo scopo di assegnare al progetto contemporaneo una base linguistica invisibile, un alfabeto che strutturi la costruzione del nuovo
