摘要：

随着LHC共振搜索的结果为零，物理学潜在的焦点现在正转向对非共振现象的解释。这种转变的一个例子是电子资金转移方案越来越受欢迎。由于良好的积分亮度和对探测器的出色理解，我们可以开始这样的计划，这将使这些搜索随着大型强子对撞机的继续而变得更加激烈。在本文中，我们提供了一个框架来执行这种解释的一组不同的情况下，包括{ \it 1。}在低能量下用导数展开描述的一般重新物理，例如EFT方法，{ \it 2.）}具有导数耦合的非常轻的粒子，例如轴子或其他轻的伪戈德斯通玻色子，以及{ \it 3.）}准连续共振的影响，这可能来自许多强耦合理论，额外的维度模型，钟表机构设置和它们的解构表兄弟。这些方案是不等价的，尽管所有的非共振，虽然其中一些之间的匹配是可能的，我们在本文中提供它。

英文摘要：

With null results in resonance searches at the LHC, the physics potential focus is now shifting towards the interpretation of non-resonant phenomena. An example of such shift is the increased popularity of the EFT programme. We can embark on such programme owing to good integrated luminosity and an excellent understanding of the detectors, which will allow these searches to become more intense as the LHC continues. In this paper we provide a framework to perform this interpretation in terms of a diverse set of scenarios, including {\it 1.) } generic heavy new physics described at low energies in terms of a derivative expansion, such as in the EFT approach, {\it 2.)} very light particles with derivative couplings, such as axions or other light pseudo-Goldstone bosons, and {\it 3.)} the effect of a quasi-continuum of resonances, which can come from a number of strongly-coupled theories, extra-dimensional models, clockwork set-ups and their deconstructed cousins. These scenarios are not equivalent despite all non-resonant, although the matching among some of them is possible and we provide it in this paper.
