Search for Tau Flavour Violation at the LHC

E. Carquin, J. Ellis, M. E. Gomez +2

We explore the prospects for searches at the LHC for sparticle decays that violate lepton number, in the light of neutrino oscillation data and the seesaw model for neutrino ma…

Perturbative nuclear physics

Silas R. Beane, David B. Kaplan, Aleksi Vuorinen

We present a new formulation of effective field theory for nucleon-nucleon (NN) interactions which treats pion interactions perturbatively, and we offer evidence that the expansion…

Vacuum Stability with Tachyonic Boundary Higgs Masses in No-Scale Supersymmetry or Gaugino Mediation

Jason L. Evans, David E. Morrissey, James D. Wells

No-scale supersymmetry or gaugino mediation augmented with large negative Higgs soft masses at the input scale provides a simple solution to the supersymmetric flavor problem while…

Effective Field Theories and Matching for Codimension-2 Branes

C. P. Burgess, D. Hoover, C. de Rham +1

It is generic for the bulk fields sourced by branes having codimension two and higher to diverge at the brane position, much as does the Coulomb potential at the position of its so…

Chiral symmetry breaking and the Banks--Casher relation in lattice QCD with Wilson quarks

Leonardo Giusti, Martin Lüscher

The Banks--Casher relation links the spontaneous breaking of chiral symmetry in QCD to the presence of a non-zero density of quark modes at the low end of the spectrum of the Dirac…

Hierarchical Soft Terms and Flavor Physics

Gian F. Giudice, Marco Nardecchia, Andrea Romanino

We study the framework of hierarchical soft terms, in which the first two generations of squarks and sleptons are heavier than the rest of the supersymmetric spectrum. This scheme…

Quality factor analysis and optimization of digital filtering signal reconstruction for liquid ionization calorimeters

Marco Delmastro

The Optimal Filtering (OF) reconstruction of the sampled signals from a particle detector such as a liquid ionization calorimeter relies on the knowledge of the normalized pulse sh…

Micro Black Holes and the Democratic Transition

Gia Dvali, Oriol Pujolas

Unitarity implies that the evaporation of microscopic quasi-classical black holes cannot be universal in different particle species. This creates a puzzle, since it conflicts with…

Diffraction at TOTEM

G. Antchev, P. Aspell, V. Avati +72

The TOTEM experiment at the LHC measures the total proton-proton cross section with the luminosity-independent method and the elastic proton-proton cross-section over a wide |t|-ra…

Realistic sterile neutrino dark matter with keV mass does not contradict cosmological bounds

Alexey Boyarsky, Julien Lesgourgues, Oleg Ruchayskiy +1

Previous fits of sterile neutrino dark matter models to cosmological data assumed a peculiar production mechanism, which is not representative of the best-motivated particle physic…

First results on angular distributions of thermal dileptons in nuclear collisions

NA60 Collaboration, R. Arnaldi, K. Banicz +50

The NA60 experiment at the CERN SPS has studied dimuon production in 158A GeV In-In collisions. The strong excess of pairs above the known sources found in the complete mass region…

Thermal dileptons in high-energy nuclear collisions

Sanja Damjanovic

Clear signs of excess dileptons above the known sources were found at the SPS since long. However, a real clarification of these observations was only recently achieved by NA60, me…

NA60 results on thermal dimuons

NA60 Collaboration, R. Arnaldi, K. Banicz +50

The NA60 experiment at the CERN SPS has measured muon pairs with unprecedented precision in 158A GeV In-In collisions. A strong excess of pairs above the known sources is observed…

Birefringence, CMB polarization and magnetized B-mode

Massimo Giovannini, Kerstin E. Kunze

Even in the absence of a sizable tensor contribution, a B-mode polarization can be generated because of the competition between a pseudo-scalar background and pre-decoupling magnet…

Studying the Sivers function by model calculations

A. Courtoy, S. Scopetta, V. Vento

A formalism is presented to evaluate the Sivers function in constituent quark models. A non-relativistic reduction of the scheme is performed and applied to the Isgur-Karl model. T…

Cosmological constraints on a light non-thermal sterile neutrino

Mario A. Acero, Julien Lesgourgues

Although the MiniBooNE experiment has severely restricted the possible existence of light sterile neutrinos, a few anomalies persist in oscillation data, and the possibility of ext…

The Volume of the Universe after Inflation and de Sitter Entropy

Sergei Dubovsky, Leonardo Senatore, Giovanni Villadoro

We calculate the probability distribution for the volume of the Universe after slow-roll inflation both in the eternal and in the non-eternal regime. Far from the eternal regime th…

Cosmic polarimetry in magnetoactive plasmas

Massimo Giovannini, Kerstin E. Kunze

Polarimetry of the Cosmic Microwave Background (CMB) represents one of the possible diagnostics aimed at testing large-scale magnetism at the epoch of the photon decoupling. The pr…

Quantum Information and Gravity Cutoff in Theories with Species

Gia Dvali, Cesar Gomez

We show that lowering of the gravitational cutoff relative to the Planck mass, imposed by black hole physics in theories with N species, has an independent justification from quant…

A Note on Unparticle Decays

A. Delgado, J. R. Espinosa, J. M. No +1

The coupling of an unparticle operator O_U to Standard Model particles opens up the possibility of unparticle decays into standard model fields. We study this issue by analyzing th…
