The Τ - Polarisation Test for the H / a → Τ + Τ − Signal at the Lhc
نویسندگان
چکیده
The correlation between the two τ-polarisations is predicted to be opposite (+ − / − +) for the H/A → τ + τ − signal, while it corresponds to the same sign combinations for the Drell-Yan (+ + / − −) and t ¯ t (−−) backgrounds. We show that this correlation can serve as a distinctive test to confirm the presence of the MSSM Higgs bosons H and A in their hadronic τ + τ − decay channels at the LHC.

Searching for H → ττ in weak boson fusion at the LHC
Weak boson fusion is a copious source of intermediate mass Higgs bosons at the LHC. The additional very energetic forward jets in these events provide for powerful background suppression tools. We analyze the H → τ τ decay mode for the Standard Model Higgs boson. A parton level analysis of the dominant physics backgrounds (mainly Z → τ τ and Drell-Yan production of τ 's) and of reducible backgr...
متن کاملUsing Tau Polarization for Charged Higgs Boson and SUSY searches at LHC
The τ polarization can be easily measured at LHC in the 1-prong hadronic τ decay channel by measuring what fraction of the τ -jet momentum is carried by the charged track. A simple cut requiring this fraction to be >0.8 retains most of the Pτ =+1 τ -jet signal while suppressing the Pτ =-1 τ -jet background and practically eliminating the fake τ background. This can be utilized to extract the ch...

The leaves of Arum conophalloides (Araceae) were used in some west areas of Iran as a dessert. The aerial parts of the herb were collected from Sahneh Mountains, Kermanshah Province, West of Iran and was hydrodistilled by Klevenger-type apparatus. Composition of the essential oil was determined by GC and GC/MS. Totally, 18 components (92% of total essential oil) were identified. The oil contain...

The simultaneous effects of inulin addition (0-4%w/w), probiotic inoculum level (1-3%v/v) and fermentation temperature (37-45°C) on the dynamic rheological properties of probiotic non-fat yogurt were studied using response surface methodology. Frequency sweep tests were performed to measure structure strength and type of structure. Linear viscoelastic range in term of strain (LVE), structure st...
متن کاملDiscovery Potential for H ± at Lhc in H ± → Τ ± Ν Decays
The discovery potential of charged Higgs from pp → tH ± in the H ± → τ ν decay channel is investigated in CMS and ATLAS. For m H ± > mt, the most relevant channels are H ± → tb and H± → τ ν. Whereas the former has the largest branching ratio it suffers of large irreducible backgrounds, while the latter offers a very clean enviroment when appropriate cuts are used. Making use of the τ polarizati...
