We combine all the available experimental information on B s mixing, including very recent tagged analyses of → J/Ψϕ by CDF and DØ collaborations. find that phase mixing amplitude deviates more than 3σ from Standard Model prediction. While no single measurement has a significance yet, constraints show remarkable agreement with combined result. This is first evidence physics beyond Model. result disfavours New Physics models Minimal Flavour Violation same significance. PACS Codes: 12.15.Ff,...
The status of the unitary triangle beyond standard model including most recent results on Deltam[s] dilepton asymmetries and width differences is presented. Even allowing for general new physics loop contributions unitarity must be very close to result. With measurements from Fermilab Tevatron, we obtain first time a significant constraint in Bs sector. We present allowed ranges DeltaF=2 processes time-dependent CP asymmetry Bs-->J/psivarphi decays.
We update the analysis of D meson mixing including latest experimental results as January 2014. derive constraints on parameters M 12, Γ12 and Φ12 that describe using all available data, allowing for CP violation. also provide posterior distributions observable appearing in physics.
Motivated by a recent paper that compares the results of analysis CKM angle $\ensuremath{\alpha}$ in frequentist and Bayesian approaches, we have reconsidered information on hadronic amplitudes, which helps constraining value standard model. We find method gives consistent irrespective parametrization amplitudes approaches are equivalent when comparing meaningful probability ranges or confidence levels. also from $B\ensuremath{\rightarrow}\ensuremath{\pi}\ensuremath{\pi}$ decays alone 95%...
The High Level Trigger (HLT) of the ATLAS experiment at Large Hadron Collider receives events which pass LVL1 trigger ∼75 kHz and has to reduce rate ∼200 Hz while retaining most interesting physics. It is a software performs reduction in two stages: LVL2 Event Filter (EF). At heart HLT Steering software. To minimise processing time data transfers it implements novel event selection strategies seeded, step-wise reconstruction early rejection. seeded by regions interest identified LVL1. These...
The ATLAS High Level Trigger's (HLT) primary function of event selection will be accomplished with a Level-2 trigger farm and an filter (EF) farm, both running software components developed in the offline reconstruction framework. While this approach provides unified framework for selection, it poses strict requirements on critical trigger. A decision must typically within 10 ms multiple processing concurrent threads. To address these constraints, prototypes have been that incorporate...

Following rigorous software design and analysis methods, an object-based architecture has been developed to derive the second- third-level trigger decisions for future ATLAS detector at LHC. The functional components within this system responsible generating elements of are algorithms running architecture. Relevant aspects reviewed along with concrete examples specific their performance in "vertical" slices various physics selection strategies.

We present the status of Unitarity Triangle Analysis (UTA), within Standard Model (SM) and beyond, with experimental theoretical inputs updated for ICHEP 2010 conference .Within SM, we find that general consistency among all constraints leaves space only to some tension (between UTA prediction measurement) in BR(B → τν), sin 2β ε K .In beyond allow New Physics (NP) effects ∆F = 2 processes.The hint NP at 2.9σ level B s -Bs mixing turns out be confirmed by update, which includes new D0 result...
