Why you need it get in twig? You can get it in corresponding controller file:

if (isset($this->request->get['a'])) {
            $a = $this->request->get['a'];
} else {
$a = '';
}
if (isset($this->request->get['b'])) {
            $b = $this->request->get['b'];
} else {
$b = '';
}

and call in twig...

{{ a }} {{ b }}
