Confirmation d'inscription par mail

Bonjour,
s'il vous plait je suis débutant en laravel , j'ai creé un projet laravel 5.2.27

Ce que je fais

je suis en train de faire une validation d'inscription par mail avec un Event
mais je comprends pas quoi passer en parametre , voici mon code

class RegsiterConfirmation extends Event
{
    use SerializesModels;

    public $user;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct( User $user)
    {
        $this->user=$user;

    }

    /**
     * Get the channels the event should be broadcast on.
     *
     * @return array
     */
    public function broadcastOn()
    {
        return [];
    }
}

class EmailConfirmation
{
    /**
     * Create the event listener.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Handle the event.
     *
     * @param  RegsiterConfirmation  $event
     * @return void
     */
    public function handle(RegsiterConfirmation $event)
    {
        $user=$event->user;
        $email=$user->email;
        \Mail::send('emails.welcom',,array('name'=>$user->name),function($message) use ($email) {

                $message->to( $email,'mail Confirmation')->subject('mail Confirmation') ;

                });
    }
}

et ça le code du controlleur 
<?php

namespace App\Http\Controllers\Auth;

use App\User;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;

use App\Events\RegsiterConfirmation ;

class AuthController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Registration & Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users, as well as the
    | authentication of existing users. By default, this controller uses
    | a simple trait to add these behaviors. Why don't you explore it?
    |
    */

    use AuthenticatesAndRegistersUsers, ThrottlesLogins;

    /**
     * Where to redirect users after login / registration.
     *
     * @var string
     */
    protected $redirectTo = '/';

    /**
     * Create a new authentication controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware($this->guestMiddleware(), ['except' => 'logout']);
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);

   // Event::fire(new RegsiterConfirmation() ;

    }

  //  Event::fire(new RegsiterConfirmation(create()) ) ;
}
