20th January 2014
My PhD
Joint theoretical (Granada, R. Pittau) and experimental
(Valencia, J. Fuster) PhD in particle physics.
Part of the
project:
I
Goal: to measure t Yukawa coupling in pp → t t̄H
I
Tools: new MC@NLO, top physics, Higgs physics,
boosted objects, ...
LYukawa = −λt t̄ H t
Boosted ttH analysis
First step: reproduce pp → ttH(bb) results
(arXiv: 0910.5472v2)

Other people are trying to reproduce same results and check
if it is possible to see a signal with real datas.

Change of ATLAS analysis model for Run2 of the LHC
−→
“Migrate the analysis for JMS/JMR uncertainty based on
semileptonic top events to xAOD and provide
recommendations on these uncertainties based on 2015
datas”
To do list:
I
Complete boosted ttH(bb) analysis. Normalization &
issues in MCs samples.
I
Just arrived new MC samples to work with to
extrapolate JMS and JMR uncertainties. (waiting for
access to the Grid).
