The phenomenological investigation of noncommutative space-time in the laboratory frame is presented. We formulate the apparent time variation of noncommutativity parameter θμν in the laboratory frame due to the earth’s rotation. Furthermore, in the noncommutative QED, we discuss how to probe the electric-like component θE=(θ01,θ02,θ03) by the process $e^-e^+\rightarrow\gamma\gamma$ at future e-e+ linear collider. We may determine the magnitude and the direction of θE by detailed study of the… 
Location and direction dependent effects in collider physics from noncommutativity
We examine the leading order noncommutative corrections to the differential and total cross sections for e{sup +}e{sup -{yields}}qq. After averaging over the Earth's rotation, the results depend on
Neutrino-electron scattering in noncommutative space
Neutral particles can couple with the U(1) gauge field in the adjoint representation at the tree level if the space-time coordinates are noncommutative (NC). Considering neutrino-photon coupling in
Hawking radiation as tunneling from a Vaidya black hole in noncommutative gravity
In the context of a noncommutative model of coordinate coherent states, we present a Schwarzschild-like metric for a Vaidya solution instead of the standard Eddington-Finkelstein metric. This leads
TeV scale implications of non commutative space time in laboratory frame with polarized beams
We analyze e+e− → γγ, e−γ → e−γ and γγ → e+e− processes within the Seiberg-Witten expanded noncommutative scenario using polarized beams. With unpolarized beams the leading order effects of non
Planck-scale nonthermal correlations in a noncommutative geometry inspired Vaidya black hole
Using the noncommutative geometry inspired Vaidya metric obtained in terms of coordinate coherent states and also utilizing the generalized uncertainty principle (GUP), we show that the nonthermal
Search for associated production of Higgs with Z boson in the noncommutative Standard Model at linear colliders
We study the associated Higgs production with Z boson at future linear colliders in the framework of the minimal noncommutative standard model. Using the Seiberg–Witten map, we calculate the
On the noncommutative geometry in quantum mechanics
In this paper, we presented and reviewed a formalism that plays a central role in most of the investigations concerning noncommutative geometry. We presented existing methods that successfully allow
Noncommutative Black Holes, The Final Appeal To Quantum Gravity: A Review
We present the state of the art regarding the relation between the physics of Quantum Black Holes and Noncommutative Geometry. We start with a review of models proposed in the literature for
Probing space–time noncommutativity in the top quark pair production at e+e- collider
The forward–backward asymmetry observed in the top quark pair production at the Fermilab Tevatron points toward the existence of beyond the standard model physics. We have studied the top quark pair


Compton scattering in noncommutative space-time at the Next Linear Collider
We study the Compton scattering in the noncommutative counter part of QED (NC QED). Interactions in NC QED have momentum dependent phase factors and the gauge fields have Yang-Mills type couplings,
Testing spatial noncommutativity via the Aharonov-Bohm effect
The possibility of detecting noncommutative space relics is analyzed using the Aharonov-Bohm effect. We show that, if space is noncommutative, the holonomy receives nontrivial kinematical corrections
C, P, and T invariance of noncommutative gauge theories
The invariance of the noncommutative gauge theories under C, P, and T transformations is studied and it is shown that the CPT invariance holds for general noncommUTative space-time.
Signals for noncommutative QED in egamma and gammagamma collisions
We study the effects of non-commutative QED (NCQED) in fermion pair production, gamma + gamma -> f + bar{f} and Compton scattering, e + gamma -> e + gamma. Non-commutative geometries appear naturally
String theory and noncommutative geometry
We extend earlier ideas about the appearance of noncommutative geometry in string theory with a nonzero B-field. We identify a limit in which the entire string dynamics is described by a minimally
Noncommutative QED and anomalous dipole moments
We study QED on noncommutative spaces, NCQED. In particular we present the detailed calculation for the noncommutative electron-photon vertex and show that the Ward identity is satisfied. We discuss
Signatures of noncommutative QED at photon colliders
In this paper we study non-commutative (NC) QED signatures at photon colliders through pair production of charged leptons(l + l ) and charged scalars(H + H ). The NC corrections for the fermion pair
