Hi all,
Thanks Mats for your prompt answer.
But I don't understand what i must do. I tried this help but no results.
Here is a new extract from my file. Is it better?
If not, I  can send the complete file.

 \version "2.8.5"

    upper = \relative c'' {
      \clef treble
      \key e \major
      \time 2/4
   <<{e16\arpeggio^\( dis\) cis^.^\( b^.\) b8 b16^.^\( cis^.\)} 
\\{a4\arpeggio b16_\( a\) gis_._\( fis_._\)}>>
}

    lower = \relative c {
      \clef treble
      \key e \major
      \time 2/4
   <b' fis'>4._\( dis8\)
}

    \score {
      \context PianoStaff <<
   \set PianoStaff.connectArpeggios = ##t
  \set PianoStaff.instrument = \markup{ \fontsize #6 {"13. "} \hspace #1.0
}
        \context Staff=upper \upper
        \context Staff=lower <<
          \clef bass
          \lower
        >>

      >>
      \layout { }
}
