	abstract = {The fraction of Lyman-\${\textbackslash}alpha\$ emitters among the galaxy population has 
been found to increase from \$z{\textbackslash}sim0\$ to \$z{\textbackslash}sim6\$ and drop dramatically
at \$z{\textgreater}6\$. This drop has been interpreted as an effect of an
increasingly neutral intergalactic medium with increasing redshift,
while a LyC escape fraction evolving with redshift. We report the result
of a large VLT/FORS2 program aiming to confirm spectroscopically a large
galaxy sample at \$z{\textbackslash}geq6\$ that has been selected in several independent
fields through the Lyman Break technique. Combining those data with
archival data, we create a large and homogeneous sample of \$z{\textbackslash}sim6\$
galaxies (\$N=127\$), complete in terms of Ly\${\textbackslash}alpha\$ detection at
\${\textgreater}95{\textbackslash}\%\$ for EW(Ly\${\textbackslash}alpha){\textbackslash}geq25{\textbackslash}AA\$. We use this sample to derive a
new measurement of the LAE fraction at \$z{\textbackslash}sim6\$ and derive the physical
properties of these galaxies through spectral energy distribution
fitting. We find a median LAE fraction at \$z{\textbackslash}sim6\$ lower than in
previous studies. The main difference between LAEs and non-LAEs is that
the latter are significantly dustier. Using predictions of our SED
fitting code accounting for nebular emission, we find an effective
Ly\${\textbackslash}alpha\$ escape fraction
\$f{\textasciicircum}\{eff\}\_\{esc\}(Ly{\textbackslash}alpha)=0.23{\textasciicircum}\{+0.36\}\_\{-0.17\}\$ remarkably consistent
with the value derived by comparing UV luminosity function with
Ly\${\textbackslash}alpha\$ luminosity function. We conclude that the drop in the LAE
fraction from \$z{\textbackslash}sim6\$ to \$z{\textgreater}6\$ is less dramatic than previously
found and the effect of an increasing IGM neutral fraction is possibly
observed at \$5},
