abstract = {The THz dynamics of two different glasses has been studied
by means of Inelastic Neutron Scattering: the germanium
diselenide (v-GeSe2) [1], an amorphous glass belonging to
the family of continuous random network forming glasses and
the glucose (C6H12O6). In both cases two well-defined peaks
are resolved in the dynamic structure factor in a broad Q
region, below and above the position of the first sharp
diffraction peak in the static structure factor. Their
common characteristics and possible differences will be
discussed during the talk. The presence of two
pseudo-‘branches’ in glasses seems to be quite general,
but their nature is not completely understood, mainly due to
the lack of theoretical models able to provide a complete
description of this intriguing features[3]. Acknowledgment:
