Search for heavy resonances decaying into a vector boson and a Higgs boson 1 / 12

Motivazione fisicaà Modello standard non e la teoria finale (massa neutrini, materia oscura, asimmetria

materia-antimateria, gerarchia...)

à Teorie oltre il modello standard: esistenza bosoni pesanti (W′, Z′) (GUT, Composite Higgs,

Little Higgs)

Heavy Vector Triplet

• Introduzione (V0,V+,V−)

• Parametri gV (strength interazione), cH (accoppiamento a bosoni), cF (accoppiamento afermioni)

• Modello HVT-B: BR(X→ f f ) << BR(X→ VV) ≈ BR(X→ VH)

• Particelle pesanti spin-1: se producibili ad LHC, rivelabili a CMS in risonanze dibosoniche

Ricerca risonanza pesante X→ bosone vettore (V) e bosone di Higgs (H) nei dati 2015 di CMS(collisioni p− p

√s = 13 TeV di LHC)

1. X→ ZH → ``bb

2. X→ WH → `νbb

3. X→ ZH → ννbb

• H → bb: alto branching ratio (≈ 60%), V → leptoni:canale pulito

• X pesante→ topologia boostata, V-H alto momento

Conclusioni

Sommario e prospettive future

• La collaborazione CMS ha cercato risonanze pesanti di spin 1 che decadono in VH nel rangedi massa 0.8 - 4 TeV

• Si sono utilizzati i dati raccolti da CMS nel 2015, per una luminosita integrata complessiva di2.2–2.5 fb−1

• Gli stati finali esplorati includono decadimenti leptonici di V (``, `ν, νν) e adronici di H (bb)

• Limiti superiori alla sezione d’urto di produzione per branching ratio sono fissati nel range10–200 fb

• Sono escluse risonanze con masse sotto ai 2 TeV nell’ambito del modello HVT-B (gV = 3)

• I risultati restringono lo spazio dei parametri disponibile per nuova fisica nel contesto HVT

• L’analisi verra ripetuta con i dati raccolti da CMS nel 2016:

à Analisi 2015 limitata dalla bassa statistica→ previsti grandi miglioramenti nel 2016à Nel 2016: gia raccolti 10 volte piu dati del 2015

Systematic uncertainties

• Analysis limited by available statistics in data

Summary of the systematic uncertainties:

• Uncertainties coming fromαmethod (parameters, choice of the functions, extrapolation)

• Uncertainties from physics objects (JES, JER, lepton scale and resolution, b-tagging)
