Complex-Mass Definition and the Structure of Unstable Particle’s Propagator
Advances in High Energy Physics, 2015 The propagators of unstable particles are considered in framework of the convolution representation. Spectral function is found for a special case when the propagator of scalar unstable particle has Breit-Wigner form.

Twistor formulation of a massive particle with rigidity
Nuclear Physics B, 2018 A massive rigid particle model in (3+1) dimensions is reformulated in terms of twistors. Beginning with a first-order Lagrangian, we establish a twistor representation of the Lagrangian for a massive particle with rigidity.

Spin-5/2 fields in hadron physics
, 2009 We show that the Lagrangian of the free spin-5/2 field in the spinor-tensor representation with the auxiliary spinor field depends on the three arbitrary parameters.

Born‐infeld electrodynamics: Clifford number and spinor representations [PDF]
International Journal of Mathematics and Mathematical Sciences, 2002 The Clifford number formalism for Maxwell equations is considered. The Clifford imaginary unit for space‐time is introduced as coordinate independent form of fully antisymmetric fourth‐rank tensor. The representation of Maxwell equations in massless Dirac equation form is considered; we also consider two approaches to the invariance of Dirac equation ...

Quantum gravity in three dimensions, Witten spinors and the quantisation of length
Nuclear Physics B, 2018 In this paper, I investigate the quantisation of length in euclidean quantum gravity in three dimensions. The starting point is the classical hamiltonian formalism in a cylinder of finite radius. At this finite boundary, a counter term is introduced that

Journal of MathematicsSpinors can be expressed as Lie algebra of infinitesimal rotations. Spinors are also defined as elements of a vector space which carries a linear representation of the Clifford algebra typically.

Group theoretic approach to fermion production
Journal of High Energy Physics, 2019 We propose a universal group theoretic description of the fermion production through any type of interaction to scalar or pseudo-scalar. Our group theoretic approach relies on the group SU(2) × U(1), corresponding to the freedom in choosing ...

Journal of High Energy Physics, 2017 In this paper we consider tree-level gauge invariant off-shell amplitudes (Wilson line form factors) in N = 4 $$ \mathcal{N}=4 $$ SYM. For the off-shell amplitudes with one leg off-shell we present a conjecture for their Grassmannian integral ...

Interacting Vector-Spinor and Nilpotent Supersymmetry
, 2005 We formulate an interacting theory of a vector-spinor field that gauges anticommuting spinor charges \{Q_\alpha{}^I, Q_\beta{}^J \} = 0 in arbitrary space-time dimensions.
