Unconstrained Lagrangian Formulation for Bosonic Continuous Spin Theory in Flat Spacetime of Arbitrary Dimension
Hiroyuki Takata
We have discovered two unconstrained forms of free Lagrangian for continuous spin(CS) theory in arbitrary flat spacetime dimension for bosonic case. These Lagrangians, unlike that…
Generation of particle number asymmetry in expanding universe
Takuya Morozumi, Keiko I. Nagao, Apriadi Salim Adam +1
We study creation and time evolution of particle number asymmetry with nonequilibrium quantum field theory. We introduce a model of a neutral scalar and a complex scalar and it has…
BRST approach to Lagrangian construction for bosonic continuous spin field
I. L. Buchbinder, V. A. Krykhtin, H. Takata
We formulate the conditions defining the irreducible continuous spin representation of the four-dimensional Poincaré group based on spin-tensor fields with dotted and undotted indi…
A new mechanism for generating particle number asymmetry through interactions
Takuya Morozumi, Keiko I. Nagao, Apriadi Salim Adam +1
A new mechanism for generating particle number asymmetry (PNA) has been developed. This mechanism is realized with a Lagrangian including a complex scalar field and a neutral scala…
Creation and evolution of particle numberasymmetry in an expanding universe
Takuya Morozumi, Keiko I. Nagao, Apriadi Salim Adam +1
We introduce a model which may generate particle number asymmetry in an expanding Universe. The model includes CP violating and particle number violating interactions. The model co…
Time variation of particle and anti-particle asymmetry in an expanding universe
Ryuichi Hotta, Takuya Morozumi, Hiroyuki Takata
Particle number violating interactions wash out the primordial asymmetry of particle number density generated by some interaction satisfying Sakharov conditions for baryogenesis. I…
