Any suggestions on how to attach framing studs into a poured concrete

I don't think masonry nails will work here, and I don't have a Hilti gun at
my immediate disposal. Not to be picky, but I don't really want to drill
anchors in either. ...

In a similar situation I drilled for tapcon screws every 4 feet or so.
Didn't even bother with a hammer drill, though I did have to redrill one
hole when I hit a rock.

The following may be overkill, but is what is recommended around here.
Using this technique the wall won't move sideways and the joists are
free to shift over time.

The top plate should be 1/4-1/2" below the joists above to allow for
shifting. To hold the top in place drill a hole in the top plate and
put a framing nail up into the bottom of the joist above, leaving maybe
1/2" of the nail sitting below the bottom of the top plate.
