“…Radiative B decays are also characterized by the large impact of short-distance QCD corrections [375]. Considerable effort has gone into the calculation of these corrections, which are now approaching next-to-next-to-leading order (NNLO) accuracy [376][377][378][379][380][381][382][383][384][385][386][387][388]. On the experimental side, both exclusive and inclusive b → sγ branching ratios are known with good accuracy, ∼5% for B → K * γ and ∼7% forB → X s γ [389], while the situation is less favorable for b → dγ transitions: measurements are only available for exclusive channels.…”

With the advent of the LHC, we will be able to probe New Physics (NP) up to energy scales almost one order of magnitude larger than it has been possible with present accelerator facilities. While direct detection of new particles will be the main avenue to establish the presence of NP at the LHC, indirect searches will provide precious complementary information, since most probably it will not be possible to measure the full spectrum of new particles and their couplings through direct production. In particular, precision measurements and computations in the realm of flavor physics are expected to play a key role in constraining the unknown parameters of the Lagrangian of any NP model emerging from direct searches at the LHC.The aim of Working Group 2 was twofold: on the one hand, to provide a coherent up-to-date picture of the status of flavor physics before the start of the LHC; on the other hand, to initiate activities on the path towards integrating information on NP from high-p T and flavor data.This report is organized as follows: in Sect. 1, we give an overview of NP models, focusing on a few examples that have been discussed in some detail during the workshop, with a short description of the available computational tools for flavor observables in NP models. Section 2 contains a concise discussion of the main theoretical problem in flavor physics: the evaluation of the relevant hadronic matrix elements for weak decays. Section 3 contains a detailed discussion of NP effects in a set of flavor observables that we identified as "benchmark channels" for NP searches. The experimental prospects for flavor physics at future facilities are discussed in Sect. 4. Finally, Sect. 5 contains some assessEur. Phys. J. C (2008) 57: 309-492 311 ments on the work done at the workshop and the prospects for future developments.

“…The same refers to those matrix elements that involve the photonic dipole operator alone [382][383][384][385][386]. Matrix elements involving other operators are known at the NNLO either in the so-called large-β 0 approximation [387] is based on this knowledge.…”

Apotropaic Plants in the Persian Folk Culture

In the Persian culture, the acrid, pungent, and at times irritating smell of some plants have given rise to some beliefs so far as a magical and supernatural power has been attributed to them. Harmal, garlic, onion, and asafoetida are the most important herbs that are supposed to have apotropaic power to ward off vicious creatures, exorcise the evil eye, and annul magic. The paper presents a detailed description of the Iranian folk rituals and ceremonies where the above plants feature as magical elements and evil repellents par excellence. A short review of the role of these herbs in the traditional medicine is given as well. GENERAL Harmal, garhc, onion, and asafoetida are of paramount importance in the folk rituals of various regions of Iran. Strangely enough, in some rituals two or three plants are simultaneously mentioned. Almost in all cases, some major characteristics constitute the motive why these are used in the folk procedures. Most of all, they are deeply-rooted in the Persian land-both cultivated and wild. Harmal, garlic, onion, and asafoetida have protractedly been used in flavouring and seasoning the Persian foods, for which some properties have been expressed: easy digestion of the foods, stimulation of some body-related phlegm, such as sexual potency, etc. Moreover, what these herbs have in common is a property to cleanse, purify, and eliminate the animal poisons.However, what has given these four plants a unique stance in the Persian folklore and culture is the belief of Iranians in their magical potential to ward off wicked creatures, like jinns, als, and fairies. Formed as a result of a firm credence to the plants' powerful impacts, this behef has laid grounds for many ritual practices aimed at driving away such evil powers. To singe harmal beans, to burn the skin of onion and garlic,
