We analyze the degree to which parity-violating (PV) electroexcitation of the ∆(1232) resonance may be used to extract the weak neutral axial vector transition form factors. We find that the axial vector electroweak radiative corrections are large and theoretically uncertain, thereby modifying the nominal interpretation of the PV asymmetry in terms of the weak neutral form factors. We also show...

The γ-circular polarizations (Pγ) and asymmetries (Aγ) of the parity forbidden M1 + E2 γ-decays: 36Cl∗(Jπ = 2;T = 1;Ex = 1.95 MeV) → 36Cl(Jπ = 2+;T = 1; g.s.) and 36Ar∗(Jπ = 2;T = 0;Ex = 4.97 MeV) → 36Ar∗(Jπ = 2+;T = 0;Ex = 1.97 MeV) are investigated theoretically. We use the recently proposed Warburton-Becker-Brown shell-model interaction. For the weak forces we discuss comparatively different...

Large Hadron Collider (LHC) experiments this year have shown the existence of a new boson that resembles the Higgs boson. Although it is known that this particle has couplings to other particles that increase with their masses, the spin of the newly discovered boson is undetermined as of yet. The Higgs boson has been predicted to be a spin 0 particle. The LHC boson is not a spin 1 particle, sug...

The spectroscopic regularities of modern empirical data on the nonstrange mesons up to 2.4 GeV can be summarized as a systematic clustering of states near certain values of energy. It is getting evident that some unknown X-symmetry triggers the phenomenon. We perform a thorough phenomenological check of a recently proposed formula M 2 ∼ L + n, which explains the X-symmetry. A semiclassical hadr...

In this analysis, we present a search for Beyond Standard Model physics in 9.2 fb−1 of √ s=8 TeV pp collision data from the Compact Muon Solenoid at the Large Hadron Collider. In particular, we consider leptonic R-Parity violations with λ122 = 0.005 in the mSUGRA parameter space characterized by m0=1000 GeV/c2, m 1 2 =900-1400 GeV/c2, A0=0, tan β=40, μ > 0, and mtop=172 GeV/c2. This study is ca...

The spectrum of the negative-parity spin-1/2 Λ baryons is studied using lattice QCD and hadronic effective theory in a unitarized coupled-channel framework. A direct comparison between two approaches possible by considering finite volume with hadron masses mesonic decay constants that correspond to situation on lattice. Comparing energy level SU(3) flavor decompositions individual states, it fo...

Measurement of the helicity dependent elastic electron-proton scattering cross section provides a key means investigating parity violation within proton. However, such measurements exhibit potential instrumental effects associated with detection polarized recoiled protons. In particular, spin-orbit interactions massive detector induce systematic spatial shift in signal. this study, we determine...

Studies of the spin and parity quantum numbers of the Higgs boson in the WW ∗→ eνμν final state are presented, based on proton–proton collision data collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb−1 at a centre-ofmass energy of √ s = 8 TeV. The Standard Model spinparity JCP = 0++ hypothesis is compared with alternative hypothese...
