摘要：

We study tachyon field inflation in the light of the Planck + WMAP + BICEP2 + BAO joint data. While the minimally coupled tachyon field inflation is consistent with the Planck2013 data, it is not confirmed by the Planck +WMAP + BICEP2 + BAO data set. However, a nonminimally coupled tachyon field inflation is consistent with this joint data set.
