A Review of the Mass Measurement Techniques proposed for the Large Hadron Collider
We review the methods which have been proposed for measuring masses of new
particles at the Large Hadron Collider paying particular attention to the
kinematical techniques suitable for extracting mass information when invisible
particles are expected.Comment: 72 pages - in form to be published in JPhys
Re-weighing the evidence for a Higgs boson in dileptonic W-boson decays
We reconsider observables for discovering and measuring the mass of a Higgs
boson via its di-leptonic decays: H --> WW* --> l nu l nu. We define an
observable generalizing the transverse mass that takes into account the fact
that one of the intermediate W-bosons is likely to be on-shell. We compare this
new variable with existing ones and argue that it gives a significant
improvement for discovery in the region m_h < 2 m_W.Comment: 3 pages, 2 figures. Changes in v2: (i) implemented a model of
detector smearing, (ii) switched LHC simulation from 14 TeV to 7 TeV running,
(iii) presenting results for 10 rather than 3 inverse femtobarns, (iv)
corrected a typo in Fig 2 legend. Changes in v3: included published erratu
Transportation Oil Demand Consumer Preferences and Asymmetric Price Responses: Some UK Evidence
The aim of this paper is to (i) establish the role of asymmetric price decompositions in UK road transportation fuel demand, (ii) make explicit the impact of the underlying energy demand trend and (iii) disaggregate the estimation for gasoline and diesel demand as separate commodities. Dynamic UK transport oil demand functions are estimated using the Seemingly Unrelated Structural Time Series Model with decomposed prices to allow for asymmetric price responses. The importance of starting with a flexible modelling approach that incorporates both an underlying demand trend and asymmetric price response function is highlighted. Furthermore, these features can lead to different insights and policy implications than might arise from a model without them. As an example, a zero elasticity for a price-cut is found (for both gasoline and diesel) implying that price reductions do not induce demand for road transportation fuel in the UK. The paper illustrates the importance of joint modelling of gasoline and diesel demand incorporating both asymmetric price responses and stochastic underlying energy demand trends.Diesel; Asymmetry; Price; Underlying Energy Demand Trend (UEDT).
A Christian Concept of Anthropology Derived from the Johannine Literature
The problem that has been attempted to be resolved by this research was the primary evaluation of the contents of the Johannine literature in order to ascertain its teaching on anthropology with limited reference to the Westminster Confession of Faith and Herman Dooyeweerd\u27s A New Critique of Theoretical Thought.
It was hoped that the Johannine problem would shed light on the most significant problem confronting modern contemplative and speculative philosophical thought which is: \u27\u27What is the nature of man ? Indeed, from the earliest writing of man to the present day, reflections of serious thinkers have filled volumes in an attempt to resolve the central question of philosophical thought: Who is man? However, to ask and to answer that question ...means both the beginning and the end of philosophical reflection
Food Superstores, Food Deserts and Traffic Generation in the UK: A Semi-Parametric Regression Approach
This study contributes another route towards explaining and tackling ‘food desert’ effects. It features the estimation of a (semi-parametric) trip attraction model for food superstores in the UK using a composite dataset. The data comprises information from the UK Census of Population, the NOMIS (National Online Manpower Information System) archive and traffic and site-specific data from the TRICS (Trip Rate Information Computer System) databases. The results indicate that traffic to a given food superstore, ceteris paribus, increases with household car ownership, store parking provision, site size (floor space), and distance to the nearest competitor. Furthermore, increases in public transport provision are shown to be associated with increasing car trips. This latter effect is discussed in the light of planning policy for development control purposes and a role linked to the reinforcement of ‘food deserts’. The results also reveal activity-specific household economies of scope and scale. It is suggested how these may also further perpetuate unsustainable development and ‘food desert’ characteristics.Traffic Generation, Food Superstores, Food Deserts, Activity Based Travel, Sustainable Development, Modelling
m_T2 : the truth behind the glamour
We present the kinematic variable, m_T2, which is in some ways similar to the
more familiar `transverse-mass', but which can be used in events where two or
more particles have escaped detection. We define this variable and describe the
event topologies to which it applies, then present some of its mathematical
properties. We then briefly discuss two case studies which show how m_T2 is
vital when reconstructing the masses of supersymmetric particles in mSUGRA-like
and AMSB-like scenarios at the Large Hadron Collider
