Action Items:


Concerning the potential participation test for the timing layer detector. The test is scheduled for September at CERN.
The director requires presentation (by Paolo) regarding the involvement of the PD group to the test and detector. Paolo had given availability on 3/7, but probably the same week he's going to be abroad for the test(beam) of the muon detector he's working with Franco G.
The date of the presentations from the groups will be decided this the week by the director, so we'll see...

The HighLumi workshop is ongoing this week.

Framework & production

Federica presented a poster on the Big Data activities going on within the group at the latest CCR meeting in Rimini, ending up being awarded for the poster!

There'll be an extension of the Spark cluster to update the Spark version and to increase the resources for the tests ongoing by SiewYan, Jacopo, Marco.


B physics

The analysis by Stefano and Alessio has been published on PLB! Ongoing work is in progress for the analysis of the new data.

Performance plots on 2018 data to be presented at ICHEP. The BPH PAG has already pre-approved the plots, that will be included in a DPS to be presented at the next PPD meeting for the final blessing.

Unblinding of the search for tetraquarks in Y+mm (independent analysis performed with 2016 data of the same final state from Kai analysis, the latter performed with 2012 data). No excesses observed!

Giacomo Fedi has recently started playing with the BsJpsiPhi sample produced for the high lumi sensitivities studies.

Charged Higgs to top-beauty

Plenty of back-forth on the nuisances following the request for further checks by the conveners. Finally, the HIG PAG conveners have proposed to start the unblinding procedure.
As a first step, the Goodness of Fit checks have shown no issues. Moved on unblinding the plots and limits, despite there is no "visible" excess in the HT and BDT distributions, 2 mass points have the observed limits ~ 10x higher than the expected ones. All hints are pointing to some issue with the convergence of the fits by combine for these two mass points. Checks are ongoing.

Dibosons, VZ resonance (V=W,Z)

Both Lisa (2q2v) and Jacopo (2q2l) papers have received feedback from the JHEP referees, and are now addressing them.

The combination effort of all 2016 diboson analyses is still ongoing, dealing with issues in including the datacards from the VW analysis (WW and ZW, in 2q1l1v final state). ATLAS will be out with a similar paper soon.

Heavy New Physics

Matteo is presenting a status report at the High Lumi workshop at CERN


Working together with Ugo, it was decided to move the topic of the analysis from the ZH SM production to the WH SM production.
The target is going to be the WH(WW*) channel, in the SS lepton final state. Siew Yan started producing the first studies with 2016 data/MC, awaiting for the finalization of the 2017 NanoAOD MC production.

Same sign dileptons


The central shifts for the second half of 2018 did get taken in no time (less than a couple of minutes after the opening of the sign-up).


2 Virtex7 boards in LNL, connected to two different super-layers of the DT chambers in Legnaro. Andrea (Triossi) is working on the implementation of a firmware in the Kintex board to condensate the two stream of hits coming from the two Virtex7s, while Jacopo is taking care of updating the software to read the new stream.



Ongoing study of ageing/outgassing of material with monotubes.

The analysis of GIF++ testbeam data is proceeding with help of Oviedo.

Fabrizio and Franco are analyzing the currents from the monotubes to understand/model the efficiency loss due to the ageing.
