+    Find the Higgs branching ratios [attachment:h-br.pdf here].

+The Challenge
+
+Three "black boxes" are given, in the form of event files in the LHC Olympics format and a series of selected plots:
+
+    Box A : [attachment:A.lhco.gz Events] Plots: [attachment:A-lhe.pdf Parton level] [attachment:A.pdf Detector level]
+    Box B : [attachment:B.lhco.gz Events] Plots: [attachment:B-lhe.pdf Parton level] [attachment:B.pdf Detector level]
+    Box C : [attachment:C.lhco.gz Events] Plots: [attachment:C-lhe.pdf Parton lelve] [attachment:C.pdf Detector level]
+
+Black boxes contain only signal events. The students are asked to pair up the boxes above with the following models and also answer to the questions:
+
+    Model 1 : Extra Z (zp) : What its mass? Does it have Standard Model couplings to fermions?
+    Model 2 : Heavy Scalar (h): What its mass? Is it a SM Higgs?
+    Model 3 : Extra W (wp+ or wp-) : What its mass? Does it have Standard Model couplings to fermions?
+
+Useful extra information:
+
+    In the plots %$H_T=\sum ||p_T^{vis}|| + E_T^{miss}$%.
+    A SM-like Z' would decay (more or less democratically) into: jet jet (uu~,cc~,dd~,ss~,bb~), t tbar (tt~), lept+lept- (e+e-,mu+mu-,ta+ta-), neutrino anti-neutrino (ve ve~,vm vm~,vt vt~). It could also have couplings to SM W and Z, and in that case would decay in to ZZ and W+W-.
+    An Higgs couple to particles with a strength which is proportional to the particle masses. A SM-like heavy H would decay in to t tbar (tt~), W+W-, ZZ.
+    A SM-like W'+ would decay into: jet jet (ud~,cs~), t b (tb~), lept neutrino (e+ ve , mu+ vm, ta+ vt). It could also have couplings to SM W and Z, and in that case would decay in to ZW.
