==Abstract==

The experimental evidence for electromagnetic signals propagating with superluminal group velocity is recalled. Transformations of space and time depending on a synchronization parameter, <span style="font-style: italic; " class="Apple-style-span">e</span><span style="vertical-align: sub; " class="Apple-style-span">1</span>, indicate the existence of a privileged inertial system. The Lorentz transformations are obtained for a particular <span style="font-style: italic; " class="Apple-style-span">e</span><span style="vertical-align: sub; " class="Apple-style-span">1</span> different from zero. No standard experiment on relativity depends on <span style="font-style: italic; " class="Apple-style-span">e</span><span style="vertical-align: sub; " class="Apple-style-span">1</span>, but if accelerations are considered only <span style="font-style: italic; " class="Apple-style-span">e</span><span style="vertical-align: sub; " class="Apple-style-span">1</span> = 0 remains possible. The causal paradox generated by superluminal signals in the theory of relativity does not exist in the theory with&nbsp;  <div><span style="font-style: italic; " class="Apple-style-span">e</span><span style="vertical-align: sub; " class="Apple-style-span">1</span> = 0. The irrelevance of superluminal signals for the Einstein, Podolsky and Rosen paradox is pointed out.&nbsp;  </div>
