Analysis of O(p^2) Corrections to <pi pi|Q_{7,8}|K>
Vincenzo Cirigliano, Eugene Golowich
The one-loop corrections to K->pi and K->2pi matrix elements of the electroweak penguin operator are calculated. General next-to-leading order relations between the K->pi and K->2p…
Phenomenology of deflected anomaly-mediation
Riccardo Rattazzi, Alessandro Strumia, James D. Wells
We explore the phenomenology of a class of models with anomaly-mediated supersymmetry breaking. These models retain the successful flavor properties of the minimal scenario while a…
Are heavy scalars natural in minimal supergravity?
Andrea Romanino, Alessandro Strumia
It has been recently claimed that very large values of a universal soft mass term m_0 for sfermions and higgs bosons become natural when M_top is close to 175 GeV if tanβ\approx 10…
Baryogenesis through leptogenesis
Riccardo Barbieri, Paolo Creminelli, Alessandro Strumia +1
Baryogenesis by heavy-neutrino decay and sphaleron reprocessing of both baryon and lepton number is reconsidered, paying special attention to the flavour structure of the general e…
Epsilon' from supersymmetry with non universal A terms?
R. Barbieri, R. Contino, A. Strumia
In supersymmetric theories with a motivated flavour structure, we investigate the possibility that an epsilon' parameter as large as the measured value be generated without conflic…
Electromagnetic Corrections to K->pi pi II - Dispersive Matching
V. Cirigliano, J. F. Donoghue, E. Golowich
We express the leading electromagnetic corrections in K-> pi pi amplitudes as integrals over the virtual photon squared-momentum Q^2. The high Q^2 behavior is obtained via the oper…
Electromagnetic Corrections to K -> pi pi I: Chiral Perturbation Theory
V. Cirigliano, J. Donoghue, E. Golowich
An analysis of electromagnetic corrections to the (dominant) octet K -> pi pi hamiltonian using chiral perturbation theory is carried out. Relative shifts in amplitudes at the seve…
Vacuum oscillations of quasi degenerate solar neutrinos
R. Barbieri, G. Ross, A. Strumia
The atmospheric neutrino oscillations and the vacuum oscillation solution of the solar neutrino problem can be consistently described by a doubly or triply degenerate neutrino spec…
Bounds on Kaluza-Klein excitations of the SM vector bosons from electroweak tests
A. Strumia
Within a minimal extension of the SM in 4+1 dimensions, we study how Kaluza Klein excitations of the SM gauge bosons affect the electroweak precision observables. Asymmetries in Z…
Towards a lattice calculation of and
S. Capitani, M. Gockeler, R. Horsley +7
Within the framework of lattice QCD a high statistics computation of the nucleon axial and tensor charges is given. Particular attention is paid to the chiral and continuum extrapo…
Is SAX J1808.4-3658 a Strange Star ?
X. -D. Li, I. Bombaci, Mira Dey +2
One of the most important questions in the study of compact objects is the nature of pulsars, including whether they are composed of -stable nuclear matter or strange quark matt…
What is the limit on the Higgs mass?
Riccardo Barbieri, Alessandro Strumia
We obtain the bounds on all the gauge invariant, flavour symmetric, CP-even operators of dimension 6 that can affect the electroweak precision tests. For the preferred Higgs mass o…
Oscillations of three neutrinos with all Delta m^2 approx 10^{-3} eV^2
Alessandro Strumia
Oscillations of three neutrinos with all squared mass splittings around 10^{-3} eV^2 are not firmly excluded by solar neutrino experiments. We carefully verify that they are also p…
Bubble-nucleation rates for cosmological phase transitions
Alessandro Strumia, Nikolaos Tetradis
We estimate bubble-nucleation rates for cosmological phase transitions. We concentrate on the evaluation of the pre-exponential factor, for which we give approximate analytical exp…
Testing nucleation theory in two dimensions
Alessandro Strumia, Nikolaos Tetradis
We calculate bubble-nucleation rates for (2+1)-dimensional scalar theories at high temperature. Our approach is based on the notion of a real coarse-grained potential. The region o…
Neutrino mixings from a U(2) flavour symmetry
Riccardo Barbieri, Paolo Creminelli, Andrea Romanino
We extend a previously developed description of the flavour parameters in the charged fermion sector, based on a U(2) flavour symmetry, to include two main features of the neutrino…
