Low Mass X-ray Binaries with INTEGRAL, bridging classes of weakly magnetized neutron star binaries.

Low-mass X-ray binaries dominate the energy X-ray output of our Galaxy. They are ideal systems to study the details of accretion onto a compact object and phenomena occurring at the surface of neutron stars (e.g. pulsations, thermonuclear burning). During 20 years of INTEGRAL operations, the large field of view, good angular, spectral and temporal resolution of its instruments up to the hard X-ray/soft γ-ray band ensured it a key role to measure the properties of LMXBs. I will review the main results obtained from low-mass X-ray binaries hosting weakly magnetized neutron stars. In particular, I will focus on the study of the spectral states and transitions up to hard X-rays and to the discovery and characterization of several accreting and transitional millisecond pulsars.Invited talk at INTEGRAL 2022 conference, Darmstadt, 17-21 October 202
