Abstract

Many studies have been made on extensions of the standard model with B – L gauge symmetry. The addition of three singlet (right-handed) neutrinos renders it anomaly-free. It has always been assumed that the spontaneous breaking of B – L is accomplished by a singlet scalar field carrying two units of B – L charge. This results in a very natural implementation of the Majorana seesaw mechanism for neutrinos. However, there exists in fact another simple anomaly-free solution which allows Dirac or inverse seesaw neutrino masses. We show for the first time these new possibilities and discuss an application to neutrino mixing with S₃ flavor symmetry.

Gauge $B – L$ model with residual $Z_{3}$ symmetry

Journal Article Ma, Ernest ; Pollard, Nicholas ; Srivastava, Rahul ; ... - Physics Letters B

We study a gauge B–L extension of the standard model of quarks and leptons with unconventional charges for the singlet right-handed neutrinos, and extra singlet scalars, such that a residual Z₃ symmetry remains after the spontaneous breaking of B–L. The phenomenological consequences of this scenario, including the possibility of long-lived self-interacting dark matter and Z' collider signatures is discussed. Lepton number L is a familiar concept. It is usually defined as a global U (1) symmetry, under which the leptons of the standard model (SM), i.e. e,μ,τ together with their neutrinos ν_e,ν_μ,ν_τ have L=1, and all other SM particles havemore »« less

Search for heavy Majorana neutrinos in $μ^{\pm} μ^{\pm}$ + jets events in proton–proton collisions at $\sqrt{s} = 8 TeV$

Journal Article Khachatryan, V. ; Sirunyan, A. M. ; Tumasyan, A. ; ... - Physics Letters B

Our search is performed for heavy Majorana neutrinos (N) using an event signature defined by two muons of the same charge and two jets (μ^±μ^±jj). The data correspond to an integrated luminosity of 19.7 fb^-1 of proton–proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS detector at the CERN LHC. We did not observe an excess of events beyond the expected standard model background and upper limits are set on |V_μN|² as a function of Majorana neutrino mass mN for masses in the range of 40–500 GeV, where V_μN is the mixing element of the heavymore »« less

${}_{Λ}^{3}H$ and ${}_{\bar{Λ}}^{3}{\overline{H}}$ production in Pb–Pb collisions at $\sqrt{s_{NN}} = 2.76 TeV$

Journal Article Adam, J. ; Adamová, D. ; Aggarwal, M. M. ; ... - Physics Letters B

© 2016 CERN for the benefit of the ALICE Collaboration. The production of the hypertriton nuclei HΛ3 and H[U+203E]Λ-3 has been measured for the first time in Pb-Pb collisions at sNN=2.76 TeV with the ALICE experiment at LHC. The p T -integrated HΛ3 yield in one unity of rapidity, dN/dy×B.R.(HΛ3→He3,π-)=(3.86±0.77(stat.)±0.68(syst.))×10-in the 0-10% most central collisions, is consistent with the predictions from a statistical thermal model using the same temperature as for the light hadrons. The coalescence parameter B 3 shows a dependence on the transverse momentum, similar to the B 2 of deuterons and the B 3 of 3 Hemore »« less

Measurement of the cross section ratio $σ_{t \bar{t} b \bar{b}} / σ_{t \bar{t} jj}$ in $p p$ collisions at $\sqrt{s} = 8 TeV$

Journal Article Khachatryan, V. ; Sirunyan, A. M. ; Tumasyan, A. ; ... - Physics Letters B

In this study, the first measurement of the cross section ratio σ_ttbb¯/σ_ttjj is presented using a data sample corresponding to an integrated luminosity of 19.6 fb^–1 collected in pp collisions at √s = 8 with the CMS detector at the LHC. Events with two leptons (e or μ ) and four reconstructed jets, including two identified as b quark jets, in the final state are selected. The ratio is determined for a minimum jet transverse momentum p_T of both 20 and 40 GeV/c.

An improved limit for $Γ_{e e}$ of $X (3872)$ and $Γ_{e e}$ measurement of $ψ (3686)$

Journal Article Ablikim, M. ; Achasov, M. N. ; Ai, X. C. ; ... - Physics Letters B

In this study, using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e⁺e⁻ → γ_ISRX(3872) → γ_ISRπ⁺π^-J/ψ via the Initial State Radiation technique. The production of a resonance with quantum numbers J^PC=1⁺⁺ such as the X(3872) via single photon e⁺e⁻ annihilation is forbidden, but is allowed by a next-to-leading order box diagram.
