## Main Question or Discussion Point

Of the twenty candidates, indicate the ones you think will prove most significant for future QG research. Since the poll is multiple choice, it's possible to vote for several papers. Abstracts follow in the next post. I've included two non-QG-related Dark Matter papers at the end because of the special interest in that topic.

http://arxiv.org/abs/1403.7482

Maité Dupuis, Florian Girelli, Etera R. Livine

(putting a non-zero cosmological constant into spinor-network terms)

http://arxiv.org/abs/1403.6396

Jaume de Haro, Jaume Amorós

(self-explanatory)

http://arxiv.org/abs/1403.3190

Emanuele Alesci, Mehdi Assanioussi, Jerzy Lewandowski

(a new LQG operator - 3D curvature, based on Regge, with good semi-classical limit.)

http://tel.archives-ouvertes.fr/docs/00/95/24/98/PDF/diss.pdf

Wolfgang Wieland

(appropriate treatment of time and Hamiltonian in 4d spin foam, recovering EPRL amplitudes)

￼

http://arxiv.org/abs/1402.6708

Wolfgang M. Wieland

(consistency check of spinorial LQG in 3d, recovers Ponzano-Regge amplitudes.)
