	abstract = {We use a newly assembled large sample of 3,545 star-forming galaxies 
with secure spectroscopic, grism, and photometric redshifts at z=1.5-2.5
to constrain the relationship between UV slope (beta) and dust
attenuation (L(IR)/L(UV)=IRX). Our sample benefits from the combination
of deep Hubble WFC3/UVIS photometry from the Hubble Deep UV (HDUV)
Legacy survey and existing photometric data compiled in the 3D-HST
survey, and extends the range of UV luminosity and beta probed in
previous UV-selected samples. IRX is measured using stacks of deep
Herschel/PACS 100 and 160 micron data, and the results are compared with
predictions of the IRX-beta relation for different assumptions of the
stellar population model and obscuration curve. We find that z=1.5-2.5
galaxies have an IRX-beta relation that is consistent with the
predictions for an SMC extinction curve if we invoke sub-solar
metallicity models that are currently favored for high-redshift
galaxies, while the commonly assumed starburst attenuation curve
over-predicts the IRX at a given beta by a factor of {\textasciitilde}3. The IRX of
high-mass (M*{\textgreater}10{\textasciicircum}9.75 Msun) galaxies is a factor of {\textgreater}4 larger than
that of low-mass galaxies, lending support for the use of stellar mass
as a proxy for attenuation. The commonly observed trend of fainter
galaxies having bluer beta may simply reflect bluer intrinsic UV slopes
for such galaxies, rather than lower obscurations. The IRX-beta for
young/low-mass galaxies implies a dust curve that is steeper than the
SMC, suggesting a lower attenuation at a given beta relative to
older/more massive galaxies. The lower attenuations and higher ionizing
photon output implied by low metallicity stellar population models point
to Lyman continuum production efficiencies, xi\_ion, that may be elevated
by a factor of {\textasciitilde}2 relative to the canonical value for L* galaxies,
aiding in their ability to keep the universe ionized at z{\textasciitilde}2. [Abridged]},
