Calculated {\\bf k}-resolved spectral functions reproduce recent angle-resolved photoemission spectroscopy (ARPES) data [D. H. Lu {\\it et al}., Nature {\\bf 455}, 81 (2008)]. Obtained effective electron mass enhancement values $m^{*}/m\\approx$ 1.9 -- 2.2 are in good agreement with infrared and optical studies [M. M.
