Rigidity of min-max minimal spheres in three-manifolds
F. C. Marques, A. Neves
In this paper we consider min-max minimal surfaces in three-manifolds and prove some rigidity results. For instance, we prove that any metric on a 3-sphere which has scalar curvatu…
A comparative measurement of and in In-In collisions at the CERN SPS
NA60 Collaboration, R. Arnaldi, K. Banicz +49
The NA60 experiment at the CERN SPS has studied meson production in In-In collisions at 158A GeV via both the and the decay channels. The yields and invers…
Nuclear dependence of light neutral meson production in p-A collisions at 400 GeV with NA60
R. Arnaldi, K. Banicz, K. Borer +51
The NA60 experiment has studied low-mass muon pair production in proton-nucleus collisions with a system of Be, Cu, In, W, Pb and U targets, using a 400 GeV proton beam at the CERN…
Deformations of the hemisphere that increase scalar curvature
S. Brendle, F. C. Marques, A. Neves
Consider a compact Riemannian manifold M of dimension n whose boundary \partial M is totally geodesic and is isometric to the standard sphere S^{n-1}. A natural conjecture of Min-O…

The NA60 experiment has studied J/ production in Indium-Indium collisions at 158 AGeV. In this paper we present an updated set of results obtained with the complete set…
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…
Rigidity of area-minimizing two-spheres in three-manifolds
H. Bray, S. Brendle, A. Neves
We give a sharp upper bound for the area of a minimal two-sphere in a three-manifold (M,g) with positive scalar curvature. If equality holds, we show that the universal cover of (M…
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…
Low Mass Dimuon Production in Indium-Indium Collisions at the CERN SPS
NA60 Collaboration, M. Floris, R. Arnaldi +48
NA60 is a fixed-target experiment at the CERN SPS which measured dimuon production in nucleus-nucleus and proton-nucleus collisions. In this paper we report on a precision measurem…
Evidence for the production of thermal muon pairs with masses above 1 GeV/c^2 in 158A GeV Indium-Indium Collisions
NA60 Collaboration, R. Arnaldi, K. Banicz +50
The yield of muon pairs in the invariant mass region 1<M<2.5 GeV/c^2 produced in heavy-ion collisions significantly exceeds the sum of the two expected contributions, Drell-Yan dim…

R. Arnaldi, K. Banicz, J. Castor +48
The NA60 experiment has studied J/psi production in p-A collisions at 158 and 400 GeV, at the CERN SPS. Nuclear effects on the J/psi yield have been estimated from the A-dependence…
Area-minimizing projective planes in three-manifolds
H. Bray, S. Brendle, M. Eichmair +1
Let (M,g) be a compact Riemannian manifold of dimension 3, and let \mathscr{F} denote the collection of all embedded surfaces homeomorphic to \mathbb{RP}^2. We study the infimum of…
