“…It is timing to study the physics related to the Higgs boson within and beyond SM. In some of the simplest extensions of the SM, such as the simple extra U(1) ′ gauge symmetry [3][4][5], the left-right models [6][7][8][9][10] and even the string * Electronic address: sps lihl@ujn.edu.cn theory [11,12], etc., a new neutral gauge boson Z ′ is introduced. The crucial test for these models is to search for the Z ′ production signal and to study its related properties.…”

Many new physics models predict the existence of extra neutral gauge bosons (Z ′ ).Inspired by the recent development on Higgs search, we study the properties of Z ′ via the Higgs and Z boson associated production. The couplings of Z ′ to quarks can be investigated through pp → Z ′ → ZH → l + l − bb process, which also provides extraordinary signal for understanding the properties of Z ′ ZH interaction. The standard model background processes can be significantly suppressed by adopting appropriate kinematic cuts. The charged lepton angular distributions are related to the ratio of chiral couplings of Z ′ to quarks via Z ′ ZH interaction.

“…Left-Right (LR) models have long provided attractive extensions to the well-tested Standard Model (SM) of particle physics [1,2,3,4,5,6,7]. A typical LR model is constructed by enlarging the SM gauge group SU(2) L × U(1) Y to the group SU(2) L × SU(2) R × U(1) B−L and thus contains an extra set of W and Z gauge bosons compared to the Standard Model, as well as an extended Higgs structure.…”

Higgs sector of the left-right model with explicitCPviolation

We explore the Higgs sector of the Minimal Left-Right (LR) Model based on the gauge group SU (2) L × SU (2) R × U (1) B−L with explicit CP violation in the Higgs potential. Since flavourchanging neutral current experiments and the small scale of neutrino masses both place stringent constraints on the Higgs potential, we seek to determine whether minima of the Higgs potential exist that are consistent with current experimental bounds. We focus on the case in which the righthanded symmetry-breaking scale is only "moderately" large, of order 15-50 TeV. Unlike the case in which the Higgs potential is CP-invariant, the CP noninvariant case does yield viable scenarios, although these require a small amount of fine-tuning. We consider a LR model supplemented by an additional U (1) horizontal symmetry, which results in a Higgs sector consistent with current experimental constraints and a realistic spectrum of neutrino masses.

“…However, the MSSM inherits some of the problems of the Standard Model, such as the generation of the neutrino masses or the strong CP problem. Both can be naturally addressed within the framework of a left-right symmetry [4][5][6][7][8][9][10][11][12][13][14]. This symmetry is favored by many extra-dimensional models, and many gauge unification scenarios, such as SO (10) or E 6 [15][16][17][18].…”

We present a complete and extensive analysis of associated chargino and neutralino production in the framework of a supersymmetric theory augmented by left-right symmetry. This model provides additional gaugino and higgsino states in both the neutral and charged sectors, thus potentially enhancing new physics signals at the LHC. For a choice of benchmark scenarios, we calculate cross sections for 7, 8 and 14 TeV. We then simulate events expected to be produced at the LHC, and classify them according to the number of leptons in the final state. We devise methods to reduce the background and compare the signals with consistently simulated events for the Minimal Supersymmetric Standard Model. We pinpoint promising scenarios where left-right symmetric supersymmetric signals can be distinguished both from background and from the Minimal Supersymmetric Standard Model events.
