DESCRIPTION:Speakers: Dr. MARCOWITH\, Alexandre (LPTA\, Université Montpe
 llier 2\, CNRS/IN2P3\, Montpellier\, France)\, Dr. KOMIN\, Nukri (LPTA\, U
 niversité Montpellier 2\, CNRS/IN2P3\, Montpellier\, France)\nIn view of 
 the discovery of HESS J1023-575 (discussed in a separate \npresentation)\,
  we\nexamine other very high energy (VHE) gamma-ray\nsources possibly asso
 ciated with massive star clusters. Particle acceleration in\nmassive star 
 forming regions can proceed at\nthe interface of two interacting winds or 
 result from a collective process\; \nmultiple\nshock acceleration or MHD t
 urbulence. \nThe gamma-ray emission can either take place in the shell at 
 the edge of the\nsuperbubble blown by the winds and multiple supernova exp
 losions. \nNon-thermal radiation from the shell structure then trace the i
 nteraction of\nenergetic particles (ions and/or electrons) with the \nsurr
 ounding interstellar matter. In particular\, HESS J1837-069 is spatially\n
 coincident with a recently discovered very massive star cluster. \nWe disc
 uss the VHE gamma-ray data resulting from H.E.S.S. observations on \nthis 
 or\nother possible such associations. We consider data in other \nwaveleng
 th domains\, in particular in X-rays\, and examine the available \nevidenc
 e that\nthe VHE emission could originate in particles accelerated by\nthe 
 above-mentioned mechanisms in massive star clusters.\n\nhttps://indico.nuc
