In this paper we report on the discovery of four gas giant planets that transit low-mass late K and early M dwarfs. The planets HATS-74Ab (TOI737b), HATS-75b (TOI552b), HATS-76b (TOI555b), and HATS-77b (TOI730b) were all discovered from the HATSouth photometric survey and follow-up using TESS and other photometric facilities. We use the new ESPRESSO facility at the VLT to confirm systems and measure their masses. We find that these planets have masses of 1.46{+/-}0.14M_J_, 0.491{+/-}0.039M_J_, 2.629{+/-}0.089M_J_, and 1.374_-0.074_^+0.100^M_J_, respectively, and radii of 1.032{+/-}0.021R_J_, 0.884{+/-}0.013R_J_, 1.079{+/-}0.031R_J_, and 1.165{+/-}0.021R_J_, respectively. The planets all orbit close to their host stars with orbital periods ranging from 1.7319days to 3.0876days. With further work, we aim to test core-accretion theory by using these and further discoveries to quantify the occurrence rate of giant planets around low-mass host stars.2022AJ....163..125Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/163/125CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/346 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/345 : Gaia DR2 (Gaia Collaboration, 2018)IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)J/A+A/415/1153 : [Fe/H] for 98 extra-solar planet-host stars (Santos+, 2004)J/ApJ/622/1102 : The planet-metallicity correlation.
