“…In this paper, which is part of a program started in a previous work [31], we propose to formulate and analyze the simple dynamics of chargeless vector matter field in a supersymmetric scenario. There are three motivation for this proposal: the lack of this approach in the literature; to get a clue on the possibility of Lorentz symmetry violation in supersymmetric theories; and the role played by the simplest case of high-spin field in field and string theories.…”

In this paper we construct and study a formulation of a chargeless complex vector matter field in a supersymmetric framework. To this aim we combine two no-chiral scalar superfields in order to take the vector component field to build the chargeless complex vector superpartner where the respective field strength transforms as matter fields by a global U(1) gauge symmetry. To the aim to deal with consistent terms without breaking the global U(1) symmetry it imposes a choice to the complex combination revealing a kind of symmetry between the choices and eliminate the extra degrees of freedom consistently with the supersymmetry. As the usual case the mass supersymmetric sector contributes as a complement to dynamics of the model. We obtain the equations of motion of the Proca's type field, for the chiral spinor fields and for the scalar field on the mass-shell which show the same mass as expected. This work establishes the firsts steps to extend the analysis of charged massive vector field in a supersymmetric scenario.

“…so the complex scalar fields d(x), f (x) and l(x) have no dynamics and arise as auxiliary fields. Thus assuming the action (27) as the sum of the redefined actions (30) and (31) and rearranging 1 the (Dirac) spinor fields Θ and Π it results in an off-shell action S os written in the following form…”

“…The overall general behavior is again observed to be qualitatively similar to that found in the case of the flat UED scenario as we see in figure 2. The above analyses for the scalar and vector fields can be immediately extended to the case of bulk fermions which are now described by the action 14) with k Ψ being the fermionic LIV parameter and V a n being the appropriate vielbein. Note that in the presence of LIV, Ψ effectively feels g 55 = 1 + k Ψ .…”

“…In such theories it is possible for LIV to manifest itself in many ways, e.g., (i) particles of various spins and flavors may have different dispersion relations correlating their mass, energy and momentum [4][5][6][7] or (ii) the general Poincare algebra itself may be deformed as in Doubly Special Relativity (for a general discussion, see [8][9][10]) such that the Planck mass is left as an invariant quantity. One way of generating LIV is through the vacuum expectation value (vev) of a tensor, usually a 4-vector, which points in a specific direction in a preferred reference frame, i.e., via spontaneous symmetry breaking [11][12][13][14][15][16]. If one imagines that maintaining rotational invariance is more sacrosanct than is boost invariance then the vev may take the time-like form ∼ (v, 0, 0, 0) in such a frame.…”

Lorentz violation in warped extra dimensions

Higher dimensional theories which address some of the problematic issues of the Standard Model (SM) naturally involve some form of D = 4 + n-dimensional Lorentz invariance violation (LIV). In such models the fundamental physics which leads to, e.g., field localization, orbifolding, the existence of brane terms and the compactification process all can introduce LIV in the higher dimensional theory while still preserving 4-d Lorentz invariance. In this paper, attempting to capture some of this physics, we extend our previous analysis of LIV in 5-d UED-type models to those with 5-d warped extra dimensions. To be specific, we employ the 5-d analog of the SM Extension of Kostelecky et al. which incorporates a complete set of operators arising from spontaneous LIV. We show that while the response of the bulk scalar, fermion and gauge fields to the addition of LIV operators in warped models is qualitatively similar to what happens in the flat 5-d UED case, the gravity sector of these models reacts very differently than in flat space. Specifically, we show that LIV in this warped case leads to a non-zero bulk mass for the 5-d graviton and so the would-be zero mode, which we identify as the usual 4-d graviton, must necessarily become massive. The origin of this mass term is the simultaneous existence of the constant non-zero AdS 5 curvature and the loss of general co-ordinate invariance via LIV in the 5-d theory. Thus warped 5-d models with LIV in the gravity sector are not phenomenologically viable.

“…Recent theoretical efforts allow for small Lorentz violations, see, e.g., [1][2][3][4][5][6]. For example, Doppler shift experiments such as the Ives-Stillwell experiment are sensitive to Lorentz violating terms in standard model extension [1,2].…”

The theoretical interest in small Lorentz violations has motivated experiments that investigate it by measuring deviations in the time dilation predicted by special relativity (SR) using high-energy ions. The main contribution of this article is to show that including the Doppler effect in the emission (which is of the same order as the time dilation effect) in the analysis leads to differences between experimental and theoretical predictions that indicate potential Lorentz violation.
