Attivit\u00e0 nelle quali \u00e8 coinvolta la Sezione INFN di Cagliari:<\/strong><\/p>\n

Gravitational Theories<\/h4>\n

Mariano Cadoni, Parul Jain, Matteo Tuveri<\/em><\/p>\n

General relativity and extensions: Black holes; Minimally coupled Einstein-Maxwell-scalar theories; Entanglement entropy vs statistical entropy and\"\" thermodynamical entropy; Ultra-compact objects such as boson stars and wormholes; Gravitational waves. Cosmology: Models for inflation; Dark energy via holographic description. Holographic description: Black brane solutions; AdS\/CFT correspondence; Domain-wall\/cosmology correspondence; Fluid\/gravity correspondence. Alternative approaches to GR: Emergent gravity.<\/p>\n

Hadron Physics<\/h4>\n

Umberto D’Alesio, Carlo Flore, Francesco Murgia, Cristian Pisano<\/em><\/p>\n

An updated extraction of the quark transversity distribution and the Collins fragmentation function from recent SIDIS and\u00a0e<\/span>+<\/span><\/span>e<\/span>\u2212<\/span><\/span><\/span><\/span>e+e\u2212<\/span><\/span>\u00a0collision data. A new study of the potential contribution of the Sivers and Collins effects to the transverse single spin asymmetry in polarized\u00a0p<\/span>p<\/span>\u2192<\/span>h<\/span>X<\/span><\/span><\/span>pp\u2192hX<\/span><\/span>\u00a0processes at large Feynman\u00a0x<\/span><\/span><\/span>x<\/span><\/span>. Study of the process dependence of the Sivers and Collins effects in polarized\u00a0p<\/span>\u2191<\/span><\/span>p<\/span>\u2192<\/span>jet<\/span><\/span>\u03c0<\/span>X<\/span><\/span><\/span>p\u2191p\u2192jet\u03c0X<\/span><\/span>\u00a0processes.

Study of TMD evolution and non-perturbative effects in transverse momentum spectra of Z-boson production in Drell-Yan.<\/p>\n

Mathematical Physics<\/h4>\n

Salvatore Mignemi, Giacomo Rosati<\/em><\/p>\n

Theory and phenomenology of models with spacetime non-commutativity. A particularly strong effort is being devoted to the study of Snyder noncommutativity and other models which lend themselves to the study of the interplay between spacetime curvature and momentum-space curvature.<\/p>\n

String Theory<\/h4>\n

Giuseppe D’Appollonio<\/em><\/p>\n

The Regge limit of inelastic string amplitudes at tree level, using both the light-cone Green-Schwarz vertex and the covariant Reggeon vertex operator. A precise interpretation of the eikonal operator through the explicit tree-level calculation of generic inelastic transitions between closed strings as they scatter off a stack of parallel\u00a0D<\/span>p<\/span><\/span><\/span><\/span>Dp<\/span><\/span>-branes.<\/p>\n

Turbulence<\/h4>\n

Piero Olla<\/em><\/p>\n

Microscopic swimming, with particular interest in the exploitation of external means (presence of an external flow, of thermal fluctuations, etc.) to aid propulsion. The dynamics of a population in an external flows, especially as regards the role of demographic fluctuations in the problem. Modelling of turbulence and turbulent transport by random fields.<\/p>\n

Miscellaneous<\/h4>\n

Soliton theory; DNA dynamics. (M. Cadoni<\/em>)<\/p>\n
