What if Charged Current Events at Large Q 2 are Observed at HERA ?
An excess of events at large Q 2 with a positron in the final state has been observed at HERA which, if confirmed, would be a signal of new physics. It is not clear at present if a signal of comparable rate is also seen in the charged current channel (with an antineutrino in the final state). In this note we analyse the implications of the presence of such a signal in models of new physics base...
متن کاملSupersymmetry and Charged Current Events at HERA
A light stop, with an R-parity-violating coupling λ131, has been suggested as an explanation of the excess in high-Q neutral current events observed at the HERA collider. We show that in this scheme a corresponding excess in charged current events — such as that reported by the H1 Collaboration — can appear naturally, without calling for the presence of light sleptons or additional R-parity-vio...
متن کاملHIGH Q2 NEUTRAL AND CHARGED CURRENT CROSS SECTIONS IN e+p COLLISIONS AT HERA
The ZEUS experiment at HERA has collected 46:6pb ?1 of e + p data during 1994 to 1997. This amount is more than twice that of data used in our previous analysis reporting an excess of high Q 2 and high x neutral current(NC) events. We have measured Born level cross sections as a function of Q 2 both for neutral and charged current(CC) deep inelastic scattering reactions using all data up to 199...
متن کاملJets in High-q2 Dis at Hera
The shapes of jets with transverse energies, E jet T , up to 45 GeV produced in neutral-current(NC) and charged-current (CC) deep inelastic e + p scattering (DIS) at Q 2 > 100 GeV 2 have been measured with the ZEUS detector at HERA. Jets are identiied using a cone algorithm in the ? ' plane with a cone radius of one unit. The jets become narrower as E jet T increases. The jet shapes in NC and C...
متن کاملMeasurement of Dijet Production at Low Q2 at HERA
The measurement of triple differential dijet cross sections in e±p interactions in the H1 experiment in the region of photon virtualities 2 < Q < 80GeV, inelasticities 0.1 < y < 0.85, jet transverse energies E∗ T 1 > 7GeV, E ∗ T 2 > 5GeV, and pseudorapidities −2.5 < η∗ 1 , η∗ 2 < 0 is presented. The analysis was done in the γ∗p centre-of-mass frame using an integrated luminosity of 57.6 pb−1. T...
