  In string theory, higher rank antisymmetric tensor fields appear as massless
excitations of closed strings. Till date there is no experimental support in
favour of their existence. In a stringy framework, starting from a warped
throat-like Klebanov-Strassler geometry, we show that all the massless higher
rank antisymmetric tensor fields are heavily suppressed due to the background
fluxes leading to their invisibility in our Universe.
