The next accelerator for particle physics experiments after the Large Hadron Collider (LHC) is likely to be a lepton collider, for example the ILC and CLIC. The next generation lepton collider will have the capability to precisely measure the properties of the Higgs boson and other particles expected to be discovered at the LHC. For example, it is not only important to discover the Higgs boson but also to measure precisely its properties like mass and decays modes. These precise measurments will help to establish if the particle found at the LHC is really the Higgs boson of the Standard Model or if it is something else. The detectors at a future lepton collider are being designed to have the required accuracy to perform these measurements. For any physics beyond the Standard Model, for example supersymmetric particles or extra dimensions, there is also a need to have precise measurements of the event properties in order to understand the underlying theory. Most of the decay modes of these particles contain many particles in their final state, clustered together in so-called 'Jets'. The capability to measure the momentum and the energy of these jets is vital to make precise measurements of particle properties. Particle flow calorimetry is a new approach combining the individual strength of both the momentum measurements in the tracking chambers and energy measurements in the calorimeters. Particle flow calorimetry can potentially improve the jet energy resolution by a factor of two compared to more traditional approaches. Particle flow calorimetry requires highly segmented detectors and sophisticated software reconstruction algorthms to utilitise this information. Essentially one attempts relate the energy deposits in all parts of the detector with the particles produced in the collision. This is challenging and requires the development of new techniques to evaluate the potential of particle flow calorimetry. Within the context of the ILC the UK is the worldwide leader in research into this new technique. This proposal aims to develop particle flow calorimetry in a more general sense and to perform and publish the definitive study on this topic. The work would have direct application to the design of next generation collider experiments.

大型强子对撞机（LHC）之后的下一个粒子物理实验加速器很可能是轻子对撞机，例如ILC和CLIC。下一代轻子对撞机将有能力精确测量希格斯玻色子和其他有望在大型强子对撞机上发现的粒子的性质。例如，发现希格斯玻色子不仅很重要，而且精确测量它的性质，如质量和衰变模式。这些精确的测量将有助于确定在LHC发现的粒子是否真的是标准模型中的希格斯玻色子，或者它是其他东西。未来的轻子对撞机上的探测器正在被设计成具有执行这些测量所需的精度。对于任何超越标准模型的物理学，例如超对称粒子或额外维度，也需要对事件属性进行精确测量，以便理解基础理论。这些粒子的大多数衰变模式都包含许多处于最终状态的粒子，它们聚集在所谓的“喷流”中。测量这些射流的动量和能量的能力对于精确测量粒子特性至关重要。粒子流量热法是一种新的方法，结合了跟踪室中的动量测量和量热计中的能量测量的单独强度。与传统方法相比，粒子流量热法可以潜在地将射流能量分辨率提高两倍。粒子流量热法需要高度分段的探测器和复杂的软件重建算法来利用这些信息。基本上，人们试图将探测器所有部分的能量沉积与碰撞中产生的粒子联系起来。这是具有挑战性的，需要开发新的技术来评估粒子流量热法的潜力。在ILC的背景下，英国是研究这一新技术的全球领导者。该提案旨在在更普遍的意义上发展粒子流量热法，并执行和发表关于这一主题的决定性研究。这项工作将直接应用于下一代对撞机实验的设计。
