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…
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…
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…
