We propose to observe the IR synchrotron emission from the jet of the X-ray binary Cyg X-1 with the IRS low resolution spectrograph on the Spitzer Space Telescope. By linking a set of 4 IR observations at different times to simultaneous radio, X-ray, and optical observations of Cyg X-1, we will be able to determine the exact shape of the synchrotron spectrum as a function of X-ray and radio flux. Understanding the broad band spectrum of Cyg X-1 will enable us to test theoretical models for jet formation in black hole binaries and to constrain fundamental parameters of jet physics. It will also allow us to asses whether the broad band synchrotron emission from jets accounts for a fair fraction of the total emission from X-ray binaries in the so called ``hard state'', as suggested in recent models. Cyg X-1 is ideally suited for such a task due to its close proximity (2.1 kpc), the well studied nature of its accretion states, the persistent presence of its VLBI resolved jet, and our ongoing frequent monitoring campaign at radio, optical, and X-ray energies. In order to be able to disentangle the jet emission from the Galactic IR background and the Rayleigh-Jeans tail of the bright companion star, we request a total of 7568 seconds or 2.1 hours of observing time.
