<field name="value">Ultra-high-energy physics is about to enter a new era thanks to the impressive results of experiments such as the Large&#xd;
High Altitude Air Shower Observatory, detecting photons of up to 1.4 × 1015 eV (PeV scale). These new results could be used to&#xd;
test deviations with respect to special relativity. While this has been already explored within the approach of Lorentz Invariance&#xd;
Violation theories, in this work we consider, for the first time, modifications due to a relativistic deformed kinematics (which appear&#xd;
in Doubly Special Relativity, or DSR, theories). In particular, we study the mean free path of very high-energy photons due to&#xd;
electron-positron pair creation when interacting with low-energy photons of the cosmic microwave background. Depending on the&#xd;
energy scale of the relativistic deformed kinematics, present (or near future) experiments can be sensitive enough to be able to&#xd;
identify deviations from special relativity.</field>
