On the Behrens--Fisher problem: A globally convergent algorithm and a finite-sample study of the Wald, LR and LM Tests
Alexandre Belloni, Gustavo Didier
In this paper we provide a provably convergent algorithm for the multivariate Gaussian Maximum Likelihood version of the Behrens--Fisher Problem. Our work builds upon a formulation…
Welfare Undominated Groves Mechanisms
Krzysztof R. Apt, Vincent Conitzer, Mingyu Guo +1
A common objective in mechanism design is to choose the outcome (for example, allocation of resources) that maximizes the sum of the agents' valuations, without introducing incenti…
Stress Tensor and Bulk Viscosity in Relativistic Nuclear Collisions
Rainer J. Fries, Berndt Müller, Andreas Schäfer
We discuss the influence of different initial conditions for the stress tensor and the effect of bulk viscosity on the expansion and cooling of the fireball created in relativistic…
Leading SU(3) breaking in lightcone distribution amplitudes
Chul Kim, Adam K. Leibovich
The lightcone formalism including SU(3) breaking effects for the light pseudoscalar mesons is studied using soft-collinear effective theory (SCET), where the conformal symmetries n…
Measurement of single charged pion production in the charged-current interactions of neutrinos in a 1.3 GeV wide band beam
K2K Collaboration, A. Rodriguez, L. Whitehead
Single charged pion production in charged-current muon neutrino interactions with carbon is studied using data collected in the K2K long-baseline neutrino experiment. The mean ener…
Systematic Comparison of Jet Energy-Loss Schemes in a 3D hydrodynamic medium
S. A. Bass, C. Gale, A. Majumder +4
We utilize a 3D hydrodynamic model to provide the medium evolution for a systematic comparison of jet energy-loss calculations in the BDMPS/ASW, HT and AMY approaches. We find that…
