We describe a five-dimensional analogue of Wigner's operator equation ${\mathbb W}_a = \lambda P_a$, where $ is the Pauli-Lubanski vector, $P_a$ energy-momentum operator, and $\lambda$ helicity massless particle. Higher dimensional generalisations are also given.

A bstract Ambitwistor strings are chiral (holomorphic) whose target is the space of complex null geodesics, ambitwistor space. We introduce twistor representations in 6 and 5 dimensions. In 6d representation naturally conformally invariant. Anomaly cancellation leads to models that describe biadjoint scalar amplitudes certain invariant gauge gravity theories, respectively 4 th order. There thre...

abstract background: administration of quality care in the aged people requires having a positive attitude toward them. numerous factors including nurses’ personality characteristics may play a role in their attitude toward the aged people. therefore, the present study investigated the association between nurses’ personality characteristics and their attitude toward the aged people. materials a...
