Single-field inflation constraints from CMB and SDSS data

Julien Lesgourgues, Fabio Finelli, Jan Hamann

We present constraints on canonical single-field inflation derived from WMAP five year, ACBAR, QUAD, BICEP data combined with the halo power spectrum from SDSS LRG7. Models with a non-scale-invariant spectrum and a red tilt n(S) < 1 are now preferred over ...

Predicting spacial similarity of freshwater fish biodiversity

Andrea Rinaldo, Mihaela Marian

A major issue in modern ecology is to understand how ecological complexity at broad scales is regulated by mechanisms operating at the organismic level. What specific underlying processes are essential for a macroecological pattern to emerge? Here, we anal ...

Lyman-alpha constraints on warm and on warm-plus-cold dark matter models

Alexey Boyarsky, Julien Lesgourgues, Oleg Ruchayskiy

We revisit Lyman-alpha bounds on the dark matter mass in Lambda Warm Dark Matter (Lambda-WDM) models, and derive new bounds in the case of mixed Cold plus Warm models (Lambda-CWDM), using a set up which is a good approximation for several theoretically wel ...

Hypothesis testing under successive refinement communication constraints

Jun Chen

We investigate the distributed successive refinement (SR) hypothesis testing problem. Bivariate hypothesis H-0 : P-XY against H-1 : PXPY, i.e., test against independence is considered, when a remote sensor sends compressed information about data stream X s ...

Evaluating Chromatic Adaptation Transform Performance

Sabine Süsstrunk

The performance of many color science and imaging algorithms are evaluated based on their mean errors. However, if these errors are not normally distributed, statistical evaluations based on the mean are not appropriate performance metrics. We present a no ...

Observation of B̄0 → D0η′ and B̄0 → D*0η′

Stewart Cole, Tagir Aushev, Sun Hee Kim, Jing Li

We report the observation of B̄0 → D 0η′ and the first observation of B̄0 → D*0η′, using 140 fb-1 of data collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. We find the branching fractions to be B(B̄0 → D0 ...

Search for an invisibly-decaying Higgs boson at LEP

Qian Wang, Aurelio Bay, Horst Vogel, Eduardo Sanchez, Zhirui Xu, Werner Lustermann, Liang Sun, Jian Zhao, Ji Hyun Kim, Zheng Wang, Matthias Weber, Xiao Wang

A search for a Higgs boson produced in e(+)e(-) collisions in association with a Z boson and decaying into invisible particles is performed. Data collected at LEP with the U detector at centre-of-mass energies from 189 to 209 GeV are used, corresponding to ...

Single- and multi-photon events with missing energy in e+e - collisions at LEP

Aurelio Bay

Single- and multi-photon events with missing energy are selected in 619 pb-1 of data collected by the L3 detector at LEP at centre-of-mass energies between 189 and 209 GeV. The cross sections of the process e +e-→νν̄γ(γ) are found to be in agreement with t ...

Search for branons at LEP

Aurelio Bay

We search, in the context of extra-dimension scenarios, for the possible existence of brane fluctuations, called branons. Events with a single photon or a single Z-boson and missing energy and momentum collected with the L3 detector in e+e- collisions at c ...

Search for doubly-charged Higgs bosons at LEP

Aurelio Bay

Doubly-charged Higgs bosons are searched for in e+e- collision data collected with the L3 detector at LEP at centre-of-mass energies up to 209 GeV. Final states with four leptons are analysed to tag the pair-production of doubly-charged Higgs bosons. No si ...
