Activity autocorrelation in financial markets. A comparative study between several models

Luigi Palatella, Josep Perello, Miquel Montero +1

We study the activity, i.e., the number of transactions per unit time, of financial markets. Using the diffusion entropy technique we show that the autocorrelation of the activity…

Non-orientable 3-manifolds of complexity up to 7

Gennaro Amendola, Bruno Martelli

We classify all closed non-orientable P2-irreducible 3-manifolds with complexity up to 7, fixing two mistakes in our previous complexity-up-to-6 classification. We show that there…

Selection of Tau Leptons with the CDF II Trigger System

S. Baroiant, M. Chertok, M. Goncharov +14

In Run II of the CDF experiment, traditional dilepton triggers are enriched by lepton (electrons or muons) plus track, di-tau and tau plus missing transverse energy triggers at Lev…

Strangeness in Neutron Stars

Ignazio Bombaci

We discuss the role of strangeness on the internal constitution and structural properties of neutron stars. In particular, we report on recent calculations of hyperon star properti…

The normal-to-planar superfluid transition in Helium 3

Martino De Prato, Andrea Pelissetto, Ettore Vicari

We study the nature of the Helium-3 superfluid transition from the normal to the planar phase, which is expected to be stabilized by the dipolar interactions. We determine the RG f…

Finite-Size Scaling in the Driven Lattice Gas

Sergio Caracciolo, Andrea Gambassi, Massimiliano Gubinelli +1

We present a Monte Carlo study of the high-temperature phase of the two-dimensional driven lattice gas at infinite driving field. We define a finite-volume correlation length, veri…

Constraints on neutrino masses from leptogenesis models

Thomas Hambye, Yin Lin, Alessio Notari +2

Upper bounds on the CP asymmetry relevant for leptogenesis are reexamined and found weaker than in previous literature, both for hierarchical and for quasi-degenerate right-handed…
