  We present a spectral analysis of the black hole candidate and X-ray
transient source Swift J1753.5 0127 making use of simultaneous observations of
XMM-Newton and Rossi X-ray Timing Explorer (RXTE) in 2006, when the source was
in outburst. The aim of this paper is to test whether a thermal component due
to the accretion disc is present in the X-ray spectrum. We fit the data with a
range of spectral models, and we find that for all of these models the fits to
the X-ray energy spectra significantly require the addition of the disc
black-body component. We also find a broad iron emission line at around 6.5
keV, most likely due to iron in the accretion disc. Our results confirm the
existence of a cool inner disc extending near or close to the innermost
circular orbit (ISCO).We further discovered broad emission lines of NVII and
OVIII at ~ 0.52 keV and 0.65 keV, respectively in the RGS spectrum of Swift
J1753.5-0127.
