In the past two weeks we had the final round of approvals for Moriond EW that is taking place during the week of Mar 17-22. The results approved are:

EXO-12-030: a search for pair-production of third generation scalar leptoquarks decaying to top quark and tau lepton pairs. Assuming unit branching fraction for the leptoquark decays to a top - tau pair, the existence of pair-produced charge −1/3 third generation leptoquarks up to a mass of 550 GeV is excluded at 95% CL.

FSQ-13-003: a measurement of the differential Drell-Yan and associated jet cross section as a function of the Drell-Yan mass in the di-muon channel for the 7 TeV dataset.

SUS-13-018 reports a search for bottom squarks directly produced in pp collisions at 8 TeV. When interpreted in the framework of simplified models, the production of bottom squarks with mass up to 700 GeV is excluded at 95% confidence level for neutralino (LSP) masses less than 50 GeV.

Eventually, TOP-14-013, the first top mass world average, has been approved during the WGM meting last week. The result reads as: m_top = 173.34 ± 0.27 (stat) ± 0.71 (syst) GeV, with a total uncertainty of 0.76 GeV. To be noted that this result only includes our 7 TeV public result.

HIG-14-003: the H->γγ process has been studied in the rare case of a Dalitz decay where a virtual photon produces a pair of muons. This process is not expected to be seen with the current statistics but might be a portal for new physics. Limits at the level of 10 times the SM expectations are set.

HIG-14-001: associated production of a top quark and the Higgs boson, decaying into photons. It directly constrains the top-Higgs coupling. No event survives the selection leading to an observed upper limit of 4.1 times the expectations in the hypothesis of a negative Yukawa coupling.

HIG-14-002: bounds on the Higgs width from off-shell ZZ events. This was our hot-topic for the Moriond EWK conference. Both ZZ in 4 leptons and 2 leptons and two neutrinos final states are used as a tool for constraining the Higgs width. This method was pioneered by F. Caola and K. Melnikov in arXiv:1307.4935 and coupled with CMS data allow to set very stringent limits Γ<4.2Γ^SM (expected Γ<8.5Γ^SM). This represents an improvement of ~200 times w.r.t. our previous (direct) limit on the Higgs width. The analysis is not yet fully approved, but the final approval meeting will happen just after the XEB meeting.

TOP-14-006: the combination of top charge asymmetries measurements from ATLAS and CMS The obtained value of AC = 0.005 ± 0.007(stat.) ± 0.006(syst.) is consistent with the Standard Model expectations.

TOP-14-001: this is the new CMS measurement of the top mass (in the lepton+jets channel) using the 8 TeV data sample. Combined with 7 TeV analysis, the resulting top mass is: m_top = 172.17 ± 0.14 (stat) ± 0.72 (syst) GeV. Its precision rivals the current world average (just approved).

The documentation for the legacy Higgs into two photons analysis is now frozen after full green-light from the ARC. The approval meeting is scheduled for the WGM on March 26th.
