Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at square root of s = 7 â€‰TeV are measured with the inner tracking system of the CMS detector at theâ€¦ (More)

In this article, we study small perturbations of the family of Friedmann-LemaÄ±Ì‚treRobertson-Walker cosmological background solutions to the coupled Euler-Einstein system with a positive cosmologicalâ€¦ (More)

In this paper the author studies the singular limit c â†’ âˆž of the family of Euler-NordstrÃ¶m systems indexed by the parameters Îº and c (EN c Îº), where Îº 2 > 0 is the cosmological constant and c is theâ€¦ (More)

In this paper the author considers the motion of a relativistic perfect fluid with self-interaction mediated by NordstrÃ¶mâ€™s scalar theory of gravity. The evolution of the fluid is determined by aâ€¦ (More)

In this article, we study small perturbations of the family of Friedmann-LemÃ¢Ä±tre-Robertson-Walker cosmological background solutions to the 1+ 3 dimensional Euler-Einstein system with a positiveâ€¦ (More)

In 3D, we study the Cauchy problem for the wave equation âˆ’âˆ‚ t Î¨ + (1 + Î¨)âˆ†Î¨ = 0 for P âˆˆ {1, 2}. We exhibit a form of Tricomi-type degeneracy formation that has not previously been studied in moreâ€¦ (More)

In this article, we study the 1 + 3 dimensional relativistic Euler equations on a pre-specified conformally flat expanding spacetime background with spatial slices that are diffeomorphic to R3. Weâ€¦ (More)

In his 2007 monograph, D. Christodoulou proved a breakthrough result giving a complete description of the formation of shock waves, starting from small, regular initial conditions, in solutions toâ€¦ (More)

Bose-Einstein correlations have been measured using samples of proton-proton collisions at 0.9 and 2.36Â TeV center-of-mass energies, recorded by the CMS experiment at the CERN Large Hadron Collider.â€¦ (More)
