The evolution of the linear and scale independent bias , based on the most popular dark matter bias models within the \Lambda CDM cosmology , is confronted to that of the Dark Energy Survey ( DES ) Luminous Red Galaxies ( LRGs ) .
Applying a \chi ^ { 2 } minimization procedure between models and data we find that all the considered linear bias models reproduce well the LRG bias data .
The differences among the bias models are absorbed in the predicted mass of the dark-matter halo in which LRGs live and which ranges between \sim 6 \times 10 ^ { 12 } h ^ { -1 } M _ { \odot } and 1.4 \times 10 ^ { 13 } h ^ { -1 } M _ { \odot } , for the different bias models .
Similar results , reaching however a maximum value of \sim 2 \times 10 ^ { 13 } h ^ { -1 } M _ { \odot } , are found by confronting the SDSS ( 2SLAQ ) Large Red Galaxies clustering with theoretical clustering models , which also include the evolution of bias .
This later analysis also provides a value of \Omega _ { m } = 0.30 \pm 0.01 , which is in excellent agreement with recent joint analyses of different cosmological probes and the reanalysis of the Planck data .
